The picture's length and width are 18 and 5. You subtract 2 instead of 1 because you are subtracting 1 on both sides of the frame.
The area of the picture is 90, and the area of the whole thing, picture and picture frame, is 20*7=140.
So, to find the area of just the picture frame, you subtract 90 from 140 to get 50in^2, which is your last answer choice.
