Question

the perimeter of a parallelogram is 72 meters. the width of the parallelogram is 4 meters less than it's length. Find the length and the width of the parallelogram​

Answer 1

Length is 18 meters and width is 14 meters

Explanation:

You can solve for the length by using the perimeter formula.

P = 2l + 2w.

You know P = 72. You also know the length is l and the width is w = l - 4.

72 = 2l + 2(l - 4)

72 = 2l + 2l - 8

72 = 4l - 8

72 = 4l

18 = l

This means the width which is 4 meters less is 18 - 4 = 14.
