Given the following shapes: a right_triangle with base 2 and height 3, a rectangle with width 2 and height 1, a rectangle with width 3 and height 6, a trapezoid with bases 3 and 2 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 2 and height 3: Area = 0.5 x 2 x 3 = 3.0
Rectangle with width 2 and height 1: Area = 2 x 1 = 2
Rectangle with width 3 and height 6: Area = 3 x 6 = 18
Trapezoid with bases 3, 2 and height 4: Area = 0.5 x (3 + 2) x 4 = 10.0</think>
