Given the following shapes: a right_triangle with base 2 and height 1, a right_triangle with base 9 and height 3, a rectangle with width 8 and height 1, a trapezoid with bases 1 and 4 and height 2, a right_triangle with base 7 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 2 and height 1: Area = 0.5 x 2 x 1 = 1.0
Right triangle with base 9 and height 3: Area = 0.5 x 9 x 3 = 13.5
Rectangle with width 8 and height 1: Area = 8 x 1 = 8
Trapezoid with bases 1, 4 and height 2: Area = 0.5 x (1 + 4) x 2 = 5.0
Right triangle with base 7 and height 6: Area = 0.5 x 7 x 6 = 21.0</think>
