Given the following shapes: a right_triangle with base 3 and height 2, a right_triangle with base 2 and height 3, a rectangle with width 2 and height 9, a trapezoid with bases 1 and 4 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 3 and height 2: Area = 0.5 x 3 x 2 = 3.0
Right triangle with base 2 and height 3: Area = 0.5 x 2 x 3 = 3.0
Rectangle with width 2 and height 9: Area = 2 x 9 = 18
Trapezoid with bases 1, 4 and height 6: Area = 0.5 x (1 + 4) x 6 = 15.0</think>
