156 is the answer because clearly there are 2 rectangles and the first is a 12 by 7 and the second one we have to figure that out but because the top is 12 and it says to take 3 off of each side you would get 6 and the l3 length is 12 so it would be 12 by 6 so yo uwould have to do 12 times 7 plus 12 times 6 and once you do that you would get 156
