perimeter_of_square = 4 x side ⇒ side = perimeter ÷ 4 = 52 cm ÷ 4 = 13 cm area_of_square = side2 = (13 cm)2 = 169 cm2
The perimeter and area don't depend on each other. Knowing one doesn't tell you the other. -- A circle with perimeter (circumference) of 20 cm has area of 31.83 cm2. -- A square with perimeter of 20 cm has area of 25 cm2 . -- A (9 x 1) rectangle has perimeter of 20 cm and area of 9 cm2 . -- A (8 x 2) rectangle has perimeter of 20 cm and area of 16 cm2 . -- A (7 x 3) rectangle has perimeter of 20 cm and area of 21 cm2 . -- A (6 x 4) rectangle has perimeter of 20 cm and area of 24 cm2 .
The sidelength of a square is the square root of its area, and its perimeter is four time this. 4 x sqrt(9 cm2) = 12 centimetres.
