HEELLLPPP ! A rectangular poster measures 42 inches by 26 inches. A frame shop fitted the poster with a half-inch mat border . Find the area of the poster ? Find the area of the mat border ?

OpenStudy (callisto):

area of poster = 42x26 = 1092 area of the border = 42.5x26.5 - 1092 = 34.25

I think the mat usually surrounds the picture, so it adds a half inch to both sides. This gives the area of the mat 43*27-1092=69
