Given the following shapes: a trapezoid with bases 8 and 3 and height 1, a right_triangle with base 6 and height 1, a right_triangle with base 3 and height 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 8, 3 and height 1: Area = 0.5 x (8 + 3) x 1 = 5.5
Right triangle with base 6 and height 1: Area = 0.5 x 6 x 1 = 3.0
Right triangle with base 3 and height 7: Area = 0.5 x 3 x 7 = 10.5</think>
