Given the following shapes: a right_triangle with base 1 and height 2, a trapezoid with bases 1 and 9 and height 4, a trapezoid with bases 3 and 1 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 1 and height 2: Area = 0.5 x 1 x 2 = 1.0
Trapezoid with bases 1, 9 and height 4: Area = 0.5 x (1 + 9) x 4 = 20.0
Trapezoid with bases 3, 1 and height 3: Area = 0.5 x (3 + 1) x 3 = 6.0</think>
