Given the following shapes: a rectangle with width 5 and height 4, a right_triangle with base 3 and height 5, a trapezoid with bases 8 and 9 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 5 and height 4: Area = 5 x 4 = 20
Right triangle with base 3 and height 5: Area = 0.5 x 3 x 5 = 7.5
Trapezoid with bases 8, 9 and height 6: Area = 0.5 x (8 + 9) x 6 = 51.0</think>
