The answer is 80 ft2. This is because length x width= area. so, 12 x 8= 96. the area of the wall is 96, but we also have the window to subtract. The window is square, so the length and width are the same. So, we can do 4 x 4, and you get 16. We need to subtract the window from the wall, so, 96 - 16= 80. Add the ft 2, and you have 80 ft2. :) Hope this helps!!! :)
