Given the following shapes: a rectangle with width 5 and height 6, a right_triangle with base 2 and height 5, a square with side 4, a trapezoid with bases 8 and 1 and height 7, a right_triangle with base 4 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 5 and height 6: Area = 5 x 6 = 30
Right triangle with base 2 and height 5: Area = 0.5 x 2 x 5 = 5.0
Square with side 4: Area = 4^2 = 16
Trapezoid with bases 8, 1 and height 7: Area = 0.5 x (8 + 1) x 7 = 31.5
Right triangle with base 4 and height 1: Area = 0.5 x 4 x 1 = 2.0</think>
