Question

You are constructing a frame for another copy of the photo. You want the frame to be the same width all the way around and the total area of the frame and photo to be 391 in.2. What should the outer dimensions of the frame be?

Answer 1

Outer dimension is 19.77 in by 19.77 in

Explanation:

Since the width is intended to be the same all round, it is a square

Hence W x W = 391in²

W² = 391

W = √391 = 19.77 in
