Given the following shapes: a trapezoid with bases 8 and 2 and height 2, a rectangle with width 4 and height 1, a right_triangle with base 4 and height 9, a right_triangle with base 4 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 8, 2 and height 2: Area = 0.5 x (8 + 2) x 2 = 10.0
Rectangle with width 4 and height 1: Area = 4 x 1 = 4
Right triangle with base 4 and height 9: Area = 0.5 x 4 x 9 = 18.0
Right triangle with base 4 and height 4: Area = 0.5 x 4 x 4 = 8.0</think>
