Given the following shapes: a rectangle with width 2 and height 3, a right_triangle with base 9 and height 2, a trapezoid with bases 3 and 3 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 2 and height 3: Area = 2 x 3 = 6
Right triangle with base 9 and height 2: Area = 0.5 x 9 x 2 = 9.0
Trapezoid with bases 3, 3 and height 1: Area = 0.5 x (3 + 3) x 1 = 3.0</think>
