As the area of a square is the length of one side squared, take the square root of 2401 to get one side's length. The perimeter is 4 times the length of one side.
The perimeter of a square with an area of 9 square feet is: 12 feet.
76 Area = 361 = (side length)^2. This tells us that the length of a side is 19. Perimeter = 4*(side length) = 4*19=76.
A square with an area of 400m has a side length of 20m. The perimeter of a square of four times the length of one of its sides. Four times 20m is 80m. Therefore, the perimeter is 80m.
If the area is a square, 1/4 of the perimeter is the length of one side. That length squared is the area. The area will be the product of two numbers whose sum is half the perimeter.
