Given the following shapes: a rectangle with width 3 and height 4, a rectangle with width 5 and height 4, a trapezoid with bases 1 and 7 and height 8, a right_triangle with base 2 and height 9, a right_triangle with base 3 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 3 and height 4: Area = 3 x 4 = 12
Rectangle with width 5 and height 4: Area = 5 x 4 = 20
Trapezoid with bases 1, 7 and height 8: Area = 0.5 x (1 + 7) x 8 = 32.0
Right triangle with base 2 and height 9: Area = 0.5 x 2 x 9 = 9.0
Right triangle with base 3 and height 6: Area = 0.5 x 3 x 6 = 9.0</think>
