Given the following shapes: a trapezoid with bases 8 and 5 and height 2, a right_triangle with base 7 and height 1, a right_triangle with base 5 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 8, 5 and height 2: Area = 0.5 x (8 + 5) x 2 = 13.0
Right triangle with base 7 and height 1: Area = 0.5 x 7 x 1 = 3.5
Right triangle with base 5 and height 2: Area = 0.5 x 5 x 2 = 5.0</think>
