Question

A rectangle has perimeter 32cm. The rectangle is three times as long as it is wide. What is the area of the rectangle

Answer 1

Answer:

Step-by-step explanation:

I will call the width W so the length L = 3W – 4

Now doesn’t that feel good?

The total perimeter is…

3W – 4 + 3W – 4 + W + W = 32

Combine terms……… 8W – 8 = 32

Add 8 to both sides…….. 8W = 40

Divide both sides by 8…… W = 5

Solution: The width is 5cm and the length is 11cm
