The area of a square whose perimeter is 36 inches is: 81 square inches.

Area = (length of a side)2 = 81 square centimeters Perimeter = 4 x (length of a side) = 36 cm.

Perimeter is 36 feet.

The area is 81 square units.

The area of square with a perimeter of 36 is 81. If the perimeter is 36, then each side must be 36 divided by 4, or 9. The area of a square is side squared, so that is 9 squared or 81.

Its area is 81 square inches.

Area of square = 81 cm2 so side of square = 9 cm and then perimeter = 4*side = 36 cm.

Perimeter of the square: 4*9 = 36 feet

If it was a square, the answer would be 81 square cm. The area will be the product of two numbers whose sum is half the perimeter.

First you have to divide the perimeter by 4, then square the solution. 81/4=20.25 20.25*20.25=410.0625 So the area equals 410.0625

The area of a room with a perimeter of 36 feet is: 81 square feet.

If the area of a square is 81, then the length of a side is 9. Add up the length of all four sides to get the perimeter: 9 + 9 + 9 + 9

A square can't have a perimeter of 36 and an area of 45. If a square's perimeter is 36,then its area is 81. If a square's area is 45, then its perimeter is about 26.83 . (rounded)A figure whose perimeter is 36 and whose area is 45 is not a square. It's a rectanglethat measures (3 by 15).

1. Okay, so we know the preimeter (all the sides added up) equal 36. 2. So we take the perimeter and devide by 4, because a square has 4 sides. (9) 3. Now that we have 9, we multiply that by another side (9) and get 81. 4. 81 is the area. ---- 36=Perimeter 36/4=Sides l * h=area 9*9=81 81=area
