Given the following shapes: a right_triangle with base 1 and height 7, a trapezoid with bases 1 and 6 and height 2, a right_triangle with base 1 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 7: Area = 0.5 x 1 x 7 = 3.5
Trapezoid with bases 1, 6 and height 2: Area = 0.5 x (1 + 6) x 2 = 7.0
Right triangle with base 1 and height 2: Area = 0.5 x 1 x 2 = 1.0</think>
