Given the following shapes: a trapezoid with bases 9 and 2 and height 4, a trapezoid with bases 5 and 7 and height 1, a trapezoid with bases 6 and 3 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 4: Area = 0.5 x (9 + 2) x 4 = 22.0
Trapezoid with bases 5, 7 and height 1: Area = 0.5 x (5 + 7) x 1 = 6.0
Trapezoid with bases 6, 3 and height 5: Area = 0.5 x (6 + 3) x 5 = 22.5</think>
