Question

The length of a rectangle is twice the width. If the perimeter of the rectangle is 60 units, find the area of the rectangle.

Answer 1

200

Let width = x
Let length = 2x
Let’s area = a

x+2x+x+2x=60

Combine the terms

6x = 60

Divide both sides by 6

x = 10

Width = 10
Length = 2*10 = 20

Area = 10*20 = 200
