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
