The width of the rectangular playground is 22 m, which is 15 m less than its length.

The width of the rectangular playground is 22 m, which is 15 m less than its length. Find the perimeter of this playground.

First, you can find the length of the playground. Since the width of the playground is 15 meters less than its length, we add 22 meters. and 15 meters. and we get 37 meters. That is, we found a side well, for example AB. Since this is a rectangle and its opposite sides are equal, then AB = CD = 37 meters, and AD = BC = 22 meters.
The perimeter is the sum of all the sides of the shape. We add all 4 sides (37 meters + 37 meters + 22 meters + 22 meters) and get 118 meters
Answer: 118 meters.
