Given the following shapes: a right_triangle with base 5 and height 1, a trapezoid with bases 3 and 1 and height 1, a trapezoid with bases 4 and 4 and height 8. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 5 and height 1: Area = 0.5 x 5 x 1 = 2.5
Trapezoid with bases 3, 1 and height 1: Area = 0.5 x (3 + 1) x 1 = 2.0
Trapezoid with bases 4, 4 and height 8: Area = 0.5 x (4 + 4) x 8 = 32.0</think>
