Given the following shapes: a right_triangle with base 1 and height 6, a rectangle with width 1 and height 7, a trapezoid with bases 1 and 2 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 1 and height 6: Area = 0.5 x 1 x 6 = 3.0
Rectangle with width 1 and height 7: Area = 1 x 7 = 7
Trapezoid with bases 1, 2 and height 2: Area = 0.5 x (1 + 2) x 2 = 3.0</think>
