How do you calculate the square feet of the area?
In a rectangular figure, square feet a generated when you multiply the length of an area by its width. So if a rectangle is 3 feet long by 5 feet wide, the area is 3 x 5 = 15 square feet. If you are dealing with a triangle, the area is half the length by the height... so a triangle 3 feet wise at the base, and 5 feet high, would be 0.5 x (3 x 5) = 0.5 x 15 = 7.5 square feet. If you are dealing with circles, the area is derived from the radius. If the radius is 3 feet, the formula is pi x r2 .... in this case pi x 32 or 9 x pi. Taking pi as 3.14 we get an area of 28.27 sq feet.
The area of a square is 9 square feet What is the length of each side?
The length of each side is 3 feet.
What is the width of a rectangle with an area of 300 square feet if it is 3 feet?
300 square feet could be 3 x 100 or 30 x 10.
The width of a rectangular rug is 3 feet If the perimeter was 22 feet what is the area of the rug?
If one side of a rectangular rug measures 3 feet then its opposite side must also measure 3 feet. Together these two sides measure 6 feet. If you deduct 6 feet from 22 feet then the remaining two sides must measure 16 feet, this means that they are each 8 feet long. A rectangle with sides of 3 feet x 8 feet has an area of 24 square feet.
What is the area of 12 feet long 7 feet wide?
If it's a rectangle, then the area = (12 x 7) = 84 square feet = 9 and 1/3 square yards
