Question

1. The area of a rectangular parking lot is 6264 m^2 .

If the length of the parking lot is 87 m , what is its width?

2. The perimeter of a rectangular pool is 342 m .
If the width of the pool is 78 m , what is its length?

Answer 1

72 m

93 m

Explanation:

1) A = length x width

6264 m² = (87 m)w

w = 6264 m²/87 m = 72 m

2) P = 2l + 2w

342 m = 2l + 2(78 m)

342 m - 156 m = 186 m = 2l

l = 186 m/2 = 93 m
