The width of the frame for the image is about 1.5 inches.

What is an area?

Area is the amount of space occupied by a two dimensional object or figure.

Let w represent the width of the frame, hence:

Length of image and frame = 7 + w + w = 2w + 7

Width of image and frame = 5 + w + w = 2w + 5

Area of width and frame = (2w + 7)(2w + 5)

80 = 4w² + 24w + 35

4w² + 24w - 45 = 0

w = 1.5 inches

The width of the frame for the image is about 1.5 inches.
