A watercolor painting is 20 inches long by 10 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 2 inches to each side of the length and the width. What is the area of the mat?

62 sq in is the area of the mat

Step-by-step explanation:

the area of the mat = total area added minus the original area of the water color painting.

length of the mat is:L = 20 in + 1 in + 1 in because 1 in  is added to each sideL = 22 inwidth of the mat is:w = 9 in + 1 in + 1inw = 11 in

Area mat = (22 in x 11 in) - ( 20 in x 9 in)

area mat = 62 sq in is the area of the mat
