Given the following shapes: a trapezoid with bases 9 and 2 and height 7, a trapezoid with bases 7 and 6 and height 4, a trapezoid with bases 6 and 2 and height 1, a right_triangle with base 5 and height 5. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 9, 2 and height 7: Area = 0.5 x (9 + 2) x 7 = 38.5
Trapezoid with bases 7, 6 and height 4: Area = 0.5 x (7 + 6) x 4 = 26.0
Trapezoid with bases 6, 2 and height 1: Area = 0.5 x (6 + 2) x 1 = 4.0
Right triangle with base 5 and height 5: Area = 0.5 x 5 x 5 = 12.5</think>
