If the perimeter of a square is 16 cm, what is the length of one side?

To find the length of one side of a square when the perimeter is known, you can use the formula for the perimeter of a square, which is given by:

Perimeter = 4 × side length.

If the perimeter is 16 cm, you can set up the equation as follows:

16 cm = 4 × side length.

To solve for the side length, divide both sides of the equation by 4:

side length = 16 cm / 4,

side length = 4 cm.

Thus, the length of one side of the square is 4 cm. This calculation directly leads to the conclusion that the answer is indeed 4 cm, confirming the correctness of the provided response.
