The width of a rectangular poster is half its length. The area of the poster is 128 square feet. What is the width of the poster?

Let the width be x/2 and the length be x: (x/2)*x = 128 Multiply both sides by 2 and remove the brackets: x2 = 256 Square root both sides: x = 16 Therefore: length = 16 feet and width = 8 feet Check: 16*8 = 128 square feet
