Given the following shapes: a right_triangle with base 9 and height 1, a trapezoid with bases 6 and 5 and height 2, a right_triangle with base 5 and height 3, a right_triangle with base 2 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 9 and height 1: Area = 0.5 x 9 x 1 = 4.5
Trapezoid with bases 6, 5 and height 2: Area = 0.5 x (6 + 5) x 2 = 11.0
Right triangle with base 5 and height 3: Area = 0.5 x 5 x 3 = 7.5
Right triangle with base 2 and height 1: Area = 0.5 x 2 x 1 = 1.0</think>
