The length of a rectangle is 12 ft. longer than twice its width. If the total length of a width and a length is 44 ft., what is

REY [17]

Width of the rectangle is 10.67 ft

<u>Step-by-step explanation:</u>

Step 1:

Let the width of the rectangle be x. Then length = 2x + 12

Given width + length = 44ft ⇒ x + 2x + 12 = 44

⇒ 44 = 3x + 12

⇒ 32 = 3x

⇒ x = 32/3 = 10.67

Width of the rectangle = 10.67 ft
