Given the following shapes: a rectangle with width 6 and height 5, a trapezoid with bases 7 and 6 and height 4, a right_triangle with base 9 and height 3, a square with side 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 6 and height 5: Area = 6 x 5 = 30
Trapezoid with bases 7, 6 and height 4: Area = 0.5 x (7 + 6) x 4 = 26.0
Right triangle with base 9 and height 3: Area = 0.5 x 9 x 3 = 13.5
Square with side 3: Area = 3^2 = 9</think>
