a rectangular picture is 7 inches wide and 7 inches long. if you put a rectangular 2-inch wide frame around the picture, What is the area of the frame?
As the frame is 2-inch wide it adds 2 inches to top, bottom and sides. So the length of area enclosed in frame is 7+2+2=11, the width is 7+2+2=11. So the area is 11*11=121 square inches
