Given the following shapes: a trapezoid with bases 9 and 6 and height 1, a rectangle with width 1 and height 6, a right_triangle with base 2 and height 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 9, 6 and height 1: Area = 0.5 x (9 + 6) x 1 = 7.5
Rectangle with width 1 and height 6: Area = 1 x 6 = 6
Right triangle with base 2 and height 7: Area = 0.5 x 2 x 7 = 7.0</think>
