Given the following shapes: a trapezoid with bases 1 and 3 and height 1, a right_triangle with base 5 and height 3, a right_triangle with base 8 and height 1, a right_triangle with base 4 and height 8, a trapezoid with bases 9 and 3 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 1, 3 and height 1: Area = 0.5 x (1 + 3) x 1 = 2.0
Right triangle with base 5 and height 3: Area = 0.5 x 5 x 3 = 7.5
Right triangle with base 8 and height 1: Area = 0.5 x 8 x 1 = 4.0
Right triangle with base 4 and height 8: Area = 0.5 x 4 x 8 = 16.0
Trapezoid with bases 9, 3 and height 2: Area = 0.5 x (9 + 3) x 2 = 12.0</think>
