Given the following shapes: a right_triangle with base 3 and height 8, a trapezoid with bases 3 and 9 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 3 and height 8: Area = 0.5 x 3 x 8 = 12.0
Trapezoid with bases 3, 9 and height 2: Area = 0.5 x (3 + 9) x 2 = 12.0</think>
