Given the following shapes: a rectangle with width 1 and height 8, a trapezoid with bases 4 and 7 and height 4, a rectangle with width 1 and height 1, a right_triangle with base 3 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 1 and height 8: Area = 1 x 8 = 8
Trapezoid with bases 4, 7 and height 4: Area = 0.5 x (4 + 7) x 4 = 22.0
Rectangle with width 1 and height 1: Area = 1 x 1 = 1
Right triangle with base 3 and height 1: Area = 0.5 x 3 x 1 = 1.5</think>
