Given the following shapes: a rectangle with width 2 and height 5, a rectangle with width 1 and height 1, a right_triangle with base 2 and height 3, a trapezoid with bases 2 and 7 and height 5. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 2 and height 5: Area = 2 x 5 = 10
Rectangle with width 1 and height 1: Area = 1 x 1 = 1
Right triangle with base 2 and height 3: Area = 0.5 x 2 x 3 = 3.0
Trapezoid with bases 2, 7 and height 5: Area = 0.5 x (2 + 7) x 5 = 22.5</think>
