Oddly enough the perimeter is 16 centimeters.
31 centimeters
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
For a square area = side2; perimeter = 4 x side. side2 = 1225 sq cm => side = sqrt(1225) = 35cm => perimeter = 4 x 35cm = 140cm.
The perimeter is 60 mm
around 33.94 centimeters
52 cm
Oddly enough the perimeter is 16 centimeters.
If the rectangle is a square, the perimeter is 48 cm. If not, there are a lot of possibilities.
The perimeter of a 900 square centimeter square is 120 centimeters.

The square root of 289 is 17 Perimeter = 4*17 = 68 cm

Area = (side)2 = 16 square centimeters Perimeter = 4 x side = 16 centimeters
The perimeter of a square with a side of length 4.76 centimeters is: (4 sides x 4.76) = 19.04 cm
