Given the following shapes: a trapezoid with bases 2 and 2 and height 9, a right_triangle with base 1 and height 3, a square with side 3, a square with side 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 2, 2 and height 9: Area = 0.5 x (2 + 2) x 9 = 18.0
Right triangle with base 1 and height 3: Area = 0.5 x 1 x 3 = 1.5
Square with side 3: Area = 3^2 = 9
Square with side 1: Area = 1^2 = 1</think>
