To find the perimeter of a square with an area of 81 square centimeters, first determine the length of one side. The area of a square is given by the formula ( \text{Area} = \text{side}^2 ). Thus, the side length is ( \sqrt{81} = 9 ) centimeters. The perimeter is calculated using the formula ( \text{Perimeter} = 4 \times \text{side} ), which gives ( 4 \times 9 = 36 ) centimeters.
Oddly enough the perimeter is 16 centimeters.

Your square must have sides of 2cm so perimeter is 8cm.
The perimeter of a 900 square centimeter square is 120 centimeters.
It is: 4*8 = 32 cm
4 root 9 ie 12 cm
Area of a square can be calculated using the formula A = a^2, where "a" is the length of a side of the square. Its perimeter is P = 4*a. 49 = a^2 => a = 7cm P = 4*7 = 28cm The perimeter of the square is 28cm.

A square with a perimeter of 32 inches has an area of 64 square inches.
9 x 9 = 81cm2Therefore, each of the 4 sides of the square measures 9cm.The perimeter is: 9 x 4 = 36cm
Oddly enough the perimeter is 16 centimeters.
The perimeter is 24 feet.

Area = (side)2 = 16 square centimeters Perimeter = 4 x side = 16 centimeters
If the rectangle is a square, the perimeter is 48 cm. If not, there are a lot of possibilities.
