As frame and picture both are in rectangular shape
So area = length (width)
Area of the frame with picture = 16 (22)
Area of the frame = 352 sq.in
Area of the picture = (12)(18)
Area of the picture = 216 sq.in
Area of the frame = Area of the frame with picture - Area of the picture
Area of the frame = 352 - 216
Area of the frame = 136 sq. in
