Question

A rectangular picture frame has a perimeter of 58 inches. The height of the frame is 18 inches. What's the width of the frame? (WRITE AND SOLVE THE EQUATION)

Answer 1

perimeter = 2l + 2w = 58 in
2(18) + 2w = 58 in
36 + 2w = 58 in
2w = 58 - 36
2w = 22 in
w = 22 divided by 2
w = 11 in

Answer 2

10 inches (each side)

Explanation:

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
