Given the following shapes: a right_triangle with base 6 and height 1, a rectangle with width 1 and height 6, a right_triangle with base 3 and height 7, a trapezoid with bases 5 and 2 and height 9. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 6 and height 1: Area = 0.5 x 6 x 1 = 3.0
Rectangle with width 1 and height 6: Area = 1 x 6 = 6
Right triangle with base 3 and height 7: Area = 0.5 x 3 x 7 = 10.5
Trapezoid with bases 5, 2 and height 9: Area = 0.5 x (5 + 2) x 9 = 31.5</think>
