Given the following shapes: a trapezoid with bases 2 and 9 and height 3, a rectangle with width 1 and height 1, a right_triangle with base 5 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 2, 9 and height 3: Area = 0.5 x (2 + 9) x 3 = 16.5
Rectangle with width 1 and height 1: Area = 1 x 1 = 1
Right triangle with base 5 and height 4: Area = 0.5 x 5 x 4 = 10.0</think>
