Given the following shapes: a right_triangle with base 3 and height 6, a rectangle with width 5 and height 4, a rectangle with width 9 and height 1, a trapezoid with bases 7 and 6 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 3 and height 6: Area = 0.5 x 3 x 6 = 9.0
Rectangle with width 5 and height 4: Area = 5 x 4 = 20
Rectangle with width 9 and height 1: Area = 9 x 1 = 9
Trapezoid with bases 7, 6 and height 1: Area = 0.5 x (7 + 6) x 1 = 6.5</think>
