The 2' X 10' perimeter yields 20 square feet of area.
18 x 10 = 180 ft^2
To calculate the square footage of a room, you multiply the length by the width. In this case, a 10 ft by 15 ft room would be 150 square feet. This is because 10 ft x 15 ft = 150 sq ft.
1400 ft^2
The area of a circle is pi*(radius)^2. If the 8 ft is the diameter, the area is pi*(4 ft)^2~=50.27 ft^2 (ft^2 is square feet)
Square footage of path = (pi*92)-(pi*72) = 100.531 square ft rounded to 3 dp
8 ft X 6 ft = 48 sq.ft. ( NOT ft^(2)).
2 ft x 4ft = 8ft²
Divide the square footage by the width in feet. Example: 20 sq. ft roll of material is made up of 10 linear feet by 2 feet in width. 20 square feet divided by 2 feet wide equals 10 linear feet and 2 feet wide. For linear feet ask yourself how long is it. 100 sq. ft. 1 foot wide would be 100 linear feet long.
Area = pi x radius squared where pi = 3.1416 radius = diameter/2 = 10 ft area = 3.1416 x 10 x 10 = 314.16 sq ft.
24' by 24' = 576 sq ft.
If the average square footage of houses is about 2700 ft^2 and the average length is about 60 ft, then it will be around 45 ft.
