Given the following shapes: a right_triangle with base 2 and height 2, a right_triangle with base 9 and height 1, a trapezoid with bases 9 and 3 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 2: Area = 0.5 x 2 x 2 = 2.0
Right triangle with base 9 and height 1: Area = 0.5 x 9 x 1 = 4.5
Trapezoid with bases 9, 3 and height 4: Area = 0.5 x (9 + 3) x 4 = 24.0</think>
