You need to order carpet for a room that has a length that is twice its width. If the area of the room is 288 ft^2, find the width of the room. 10 ft b) 13 ft c) 16 ft d) 12 ft e) 14 ft f) None of the above.

Solution

Let width = x

Then length = twice the width = 2x

Area = 288

x(2x) = 288

2x²=288

x²= 288/2 = 144

x= square root 144 = 12 ft
