The length of everything is measured in inches or feet. Feet is the plural form of the foot and is not a unit of length in the Imperial and American systems of measurement. However, when describing an architectural space - a rectangle or a square - area must be calculated using two dimensions, since area is a two-dimensional dimension. The area of ​​a room is calculated by multiplying the length and width of the room in feet. For example, if a room is 15 feet long and 12 feet wide, then the area of ​​the room is 15 times 12, which is 180 square feet.

Difference between feet and square feet

Basics Feet Vs. Square foot

Feet (plural of feet) is a non-SI unit for measuring length as specified in Imperial and American units. It is used to measure height, length and distance. Square feet is a non-SI unit for measuring area, primarily in the United States. It is the plural of a square foot, used to measure any two-dimensional space.

Symbol and calculation of feet Vs. Square foot

The international symbol for feet is "feet", while square feet are "sq ft." Or "ft 2". The area of ​​a rectangular or square room is calculated in square feet by multiplying the length and width of the room in feet. If the room is 12 feet long and 12 wide, then the area of ​​the room is (12 * 12) 144 square meters.

Foot transformation Vs. Square foot

1 foot converts to 12 inches or 0.3048 meters. Likewise, 1 square meter is equivalent to 0.092903 square meters, or 144 square inches. Area in 1 sq. Feet would be 12 * 12 inches squared. Feet is a one-dimensional unit and square feet is a two-dimensional unit for area.

Examples of feet Vs. Square foot

If the room is 15 feet long and 10 feet wide, then the area of ​​the room is calculated as:

Area = 15 × 10 = 150 square feet or 150 sq. Feet or 150 Feet 2

Summary of Feet and Square Feet

When you measure the length of everything, it is measured in inches or feet, but the area is a two-dimensional dimension, so it is calculated in two dimensions - length and width. To calculate architectural space in square feet, length and width are measured in feet and then multiplied together to give an area in square feet or 2 feet. Foot is a non-SI unit for measuring length, while square foot is unit of measure a unit of measure other than SI.

More about the area

General information

Area is a quantity geometric shape in two-dimensional space. It is used in mathematics, medicine, engineering, and other sciences, such as calculating the cross sections of cells, atoms, or pipes such as blood vessels or water pipes. In geography, area is used to compare the sizes of cities, lakes, countries, and other geographic features. Area is also used to calculate population density. Population density is defined as the number of people per unit area.

Units

Square meters

Area is measured in SI units in square meters. One square meter is the area of ​​a square with a side of one meter.

Unit square

A unit square is a square with sides of one unit. The area of ​​a unit square is also equal to one. IN rectangular system coordinates this square is in coordinates (0,0), (0,1), (1,0) and (1,1). On the complex plane, the coordinates are 0, 1, i and i+1, where i is an imaginary number.

Ar

Ap or weaving, as a measure of area, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks, when a hectare is too large. One ar is equal to 100 square meters. In some countries, this unit is called differently.

Hectare

Real estate is measured in hectares, especially land plots. One hectare equals 10,000 square meters. It has been used since the times French Revolution, and is used in the European Union and some other regions. Just like the are, in some countries a hectare is called differently.

Acre

In North America and Burma, area is measured in acres. Hectares are not used there. One acre is equal to 4046.86 square meters. An acre was originally defined as the area that a peasant with a team of two oxen could plow in one day.

Barn

Barns are used in nuclear physics to measure the cross section of atoms. One barn is equal to 10⁻²⁸ square meters. Barn is not a unit in the SI system, but it is accepted for use in this system. One barn approximately equal to the area cross-section of the uranium nucleus, which physicists jokingly called "huge as a barn." The barn in English is "barn" (pronounced barn) and from a joke of physicists this word became the name of a unit of area. This unit originated during World War II, and scientists liked it because its name could be used as a code in correspondence and telephone conversations within the framework of the Manhattan Project.

Area calculation

The area of ​​the simplest geometric shapes is found by comparing them with a square famous square... This is convenient because the area of ​​a square is easy to calculate. Some formulas for calculating the area of ​​geometric shapes, given below, are obtained in this way. Also, to calculate the area, especially a polygon, the figure is divided into triangles, the area of ​​each triangle is calculated using the formula, and then added. The area of ​​more complex shapes is calculated using mathematical analysis.

Area formulas

• Square: side squared.
• Rectangle: the product of the parties.
• Triangle (side and height known): the product of the side and the height (the distance from that side to the edge), halved. Formula: A = ½ah where A- area, a- side, and h- height.
• Triangle (two sides and the angle between them are known): the product of the sides and the sine of the angle between them, divided in half. Formula: A = ½ab sin (α), where A- area, a and b are the sides, and α is the angle between them.
• Equilateral triangle: side squared divided by 4 and multiplied by Square root out of three.
• Parallelogram: the product of the side and the height, measured from this side to the opposite.
• Trapezium: the sum of two parallel sides multiplied by the height and divided by two. Height is measured between the two sides.
• A circle: product of the square of the radius and π.
• Ellipse: product of semiaxes and π.

Calculating surface area

You can find the surface area of ​​simple volumetric figures, such as prisms, by unfolding the figure on a plane. It is impossible to obtain a sweep of the ball in this way. The surface area of ​​the ball is found using the formula by multiplying the square of the radius by 4π. It follows from this formula that the area of ​​a circle is four times less than the surface area of ​​a ball with the same radius.

Surface areas of some astronomical objects: Sun - 6.088 x 10¹² square kilometers; Earth - 5.1 x 10⁸; thus, the surface area of ​​the Earth is about 12 times less than the surface area of ​​the Sun. The lunar surface area is approximately 3.793 x 10⁷ square kilometers, which is about 13 times less than the Earth's surface area.

Planimeter

The area can also be calculated using a special device - a planimeter. There are several types of this device, for example, polar and linear. Also, planimeters are analog and digital. In addition to other functions, a scale can be entered into digital planimeters, making it easier to measure objects on a map. The planimeter measures the distance traveled along the perimeter of the measured object, as well as the direction. The distance traveled by the planimeter parallel to its axis is not measured. These devices are used in medicine, biology, engineering, and agriculture.

Theorem on the properties of areas

According to the isoperimetric theorem, of all figures with the same perimeter, the most big square by the circle. If, on the contrary, we compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the sides of a geometric shape, or a line that marks the boundaries of that shape.

Geographic features with the largest area

Country: Russia, 17,098,242 square kilometers, including land and water. The second and third largest countries are Canada and China.

City: New York is the city with the largest area at 8683 square kilometers. The second largest city is Tokyo, which covers 6993 square kilometers. The third is Chicago, with an area of ​​5,498 square kilometers.

City Square: The largest area, covering 1 square kilometer, is located in the capital of Indonesia, Jakarta. This is Medan Merdeka Square. The second largest area of ​​0.57 square kilometers is Praça doz Girazois in Palmas, Brazil. The third largest is Tiananmen Square in China, 0.44 square kilometers.

Lake: Geographers argue whether the Caspian Sea is a lake, but if so, it is the largest lake in the world with an area of ​​371,000 square kilometers. The second largest lake is Lake Superior in North America. This is one of the lakes of the Great Lakes system; its area is 82,414 square kilometers. The third largest lake is Lake Victoria in Africa. It covers an area of ​​69,485 square kilometers.
