Given the following shapes: a right_triangle with base 4 and height 3, a right_triangle with base 5 and height 1, a trapezoid with bases 8 and 2 and height 8. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 4 and height 3: Area = 0.5 x 4 x 3 = 6.0
Right triangle with base 5 and height 1: Area = 0.5 x 5 x 1 = 2.5
Trapezoid with bases 8, 2 and height 8: Area = 0.5 x (8 + 2) x 8 = 40.0</think>
