The rectangular playground in tim's school is three times as long as it is wide. the area of the playground is 75 square meters. what is the primeter of the playground?

Let x be the width of the playground, then 3x is the length of the

playground

х * 3 х = 75

3x ² = 75

x² = 25

x = 5 m (width)

5*3=15 m (length)

Perimeter = 2 (5+15) = 2*20 = 40 meters.
