Question

The length of a rectangle is 2 m greater than the width. The area is 143m^2. Find the length and the width.

Answer 1

L = 13 m W = 11 m

Explanation:

L = W + 2

area = L x W

143 = (W+2) * W

143 = W^2 + 2w

W^2 + 2W - 143 = 0

Use Quadratic Formula (a = 1 b = 2 c = - 143)

to find W = 11 m then L = 13
