Question

A rectangle is four times longer than it is wide. It has an area of 16 square meters. What are the dimensions of the rectangle?

Answer 1

The width = 2 and the length = 8

Explanation:

Let the width be x

The the length will be 4x

Area = 16

Area = l × w

16 = 4x × x

16 = 4x²

Divide both sides by 4

16/4 = x²

x² = 4

x = √4

x = 2

Therefore the width = 2 and the length = 8
