Given the following shapes: a trapezoid with bases 5 and 1 and height 3, a right_triangle with base 5 and height 2, a right_triangle with base 7 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 5, 1 and height 3: Area = 0.5 x (5 + 1) x 3 = 9.0
Right triangle with base 5 and height 2: Area = 0.5 x 5 x 2 = 5.0
Right triangle with base 7 and height 6: Area = 0.5 x 7 x 6 = 21.0</think>
