Given the following shapes: a right_triangle with base 5 and height 5, a trapezoid with bases 5 and 4 and height 8, a rectangle with width 3 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 5 and height 5: Area = 0.5 x 5 x 5 = 12.5
Trapezoid with bases 5, 4 and height 8: Area = 0.5 x (5 + 4) x 8 = 36.0
Rectangle with width 3 and height 1: Area = 3 x 1 = 3</think>
