Question

A carpenter is designing rectangular picture frames to sell at a local craft fair. The frames will be made of wood with a uniform width around the picture, and each frame will have an opening for a 5-inch by 7-inch picture.

Answer 1

Don’t know what you are wanting, but I will take a guess.
Perimeter, P = L2 + W2
5 x 2 = 10
7 x 2 = 14
10 + 14 = 24 inches of would you make a 5 by 7 frame.
