Given the following shapes: a right_triangle with base 2 and height 1, a right_triangle with base 1 and height 1, a right_triangle with base 9 and height 4, a trapezoid with bases 2 and 4 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 1: Area = 0.5 x 2 x 1 = 1.0
Right triangle with base 1 and height 1: Area = 0.5 x 1 x 1 = 0.5
Right triangle with base 9 and height 4: Area = 0.5 x 9 x 4 = 18.0
Trapezoid with bases 2, 4 and height 4: Area = 0.5 x (2 + 4) x 4 = 12.0</think>
