Question

The length of a rectangle is 3 inches more than its width, and its perimeter is 22 inches. Find the width of the rectangle.

A.) 4 in
B.) 5 in
C.) 7 in

Answer 1

The perimeter of a rectangle is the sum of all sides of the shape. It is expressed as:

P = 2l + 2w

where l is the length and is equal to 2 + w and w is the width

22 = 2(2+w) +2w
22 = 6w
w = 11/3 inches
