Given the following shapes: a rectangle with width 6 and height 4, a right_triangle with base 2 and height 7, a trapezoid with bases 1 and 5 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 6 and height 4: Area = 6 x 4 = 24
Right triangle with base 2 and height 7: Area = 0.5 x 2 x 7 = 7.0
Trapezoid with bases 1, 5 and height 3: Area = 0.5 x (1 + 5) x 3 = 9.0</think>
