1 and 8
because they are exterior angles because they are on the outside and alternate because they are on opposite sides
Area of rectangle in the middle = 12 * 9 = 108
Area of left triangle = .5 * 2 * 9 = 9
Area of right side triangle = .5 * 5 * 9 = 22.5
Total area = 108 + 9 + 22.5 = 139.5 square inches
