What is the formula for the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(length + width).

Front

If the perimeter of a rectangle is 128 inches and the width is 16 inches, how do you find the length?

Back

Use the formula P = 2(length + width). Rearranging gives length = (P/2) - width. So, length = (128/2) - 16 = 48 inches.
