Six cm per side.
For a square area = side2; perimeter = 4 x side. side2 = 1225 sq cm => side = sqrt(1225) = 35cm => perimeter = 4 x 35cm = 140cm.
The perimeter of a square is the sum of all its sides. In this case, if the perimeter is twenty centimeters, each side of the square would be five centimeters long.
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
