Given the following shapes: a right_triangle with base 5 and height 3, a trapezoid with bases 1 and 5 and height 2, a right_triangle with base 6 and height 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 5 and height 3: Area = 0.5 x 5 x 3 = 7.5
Trapezoid with bases 1, 5 and height 2: Area = 0.5 x (1 + 5) x 2 = 6.0
Right triangle with base 6 and height 7: Area = 0.5 x 6 x 7 = 21.0</think>
