Question

The perimeter of a rectangular swimming pool is 42m. The length is 5 meters more than the width. What is the length of the swimming pool?

Answer 1

Length is 13 meters

Explanation:

Length: x + 5

Width: x

2L + 2W = Perimeter

2(x+5) + 2x = 42

2x + 10 + 2x = 42

4x + 10 = 42

4x = 32

x = 8

Length: 8 + 5 = 13

Width: 8
