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.

4 in.
5 in.
7 in.

Answer 1

Answer: 4

Explanation:

Answer 2

W = 4 in

Explanation:

Here W is the width and L the length. Then L = W + 3 in.

The formula for the perimeter of a rectangle is P = 2W + 2L.

Thus, 22 in = 2(W) + 2(W + 3), which reduces to

11 in = W + W + 3 in, or

8 in = 2W, and W = 4 in
