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).

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 first step to answering this question is convert from area to length. The area of a square is L2 where L is the length of one side. In this case, L2=81, so L=9 The perimeter of a square is calculated by the expression 4L So the perimeter of this square is 9x4=36cm

9+9+9+9 = 36 units

Perimeter is 36 feet.

The area is 81 square units.

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.

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.

For a square Area = Side2 thus Side = √Area = √81 = 9cmFor a square, Perimeter = 4 x Side = 4 x 9 = 36cm

36 cm
