A picture frame is 20 inches long and 7 inches tall. It is 1 inch wide on all 4 sides. What is the area of the picture frame?

OpenStudy (anonymous):

The picture frame area is going to be 20 x 7 minus the area of the picture: (20 x 7) - (20 - 2) x (7 - 2) This "2" is from a decrease in the height and width of 1 inch on each side. (20 x 7) - (18 x 5)
