Question

What is the area of the grey matting in this 16” by 20” picture frame if the picture to be framed is 11” x 14”?

Answer 1

166 square inches

Explanation:

The area of the matting is the difference between the area of the frame and the area of the picture.

Answer 2

Find the area [ a = bh ] of both then subtract.

16 * 20 = 320

11 * 14 = 154

320 - 154 = 166"

Best of Luck!
