Given the following shapes: a rectangle with width 1 and height 3, a trapezoid with bases 5 and 3 and height 6, a right_triangle with base 4 and height 9. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 1 and height 3: Area = 1 x 3 = 3
Trapezoid with bases 5, 3 and height 6: Area = 0.5 x (5 + 3) x 6 = 24.0
Right triangle with base 4 and height 9: Area = 0.5 x 4 x 9 = 18.0</think>
