Given the following shapes: a right_triangle with base 9 and height 2, a square with side 1, a trapezoid with bases 5 and 1 and height 9. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 9 and height 2: Area = 0.5 x 9 x 2 = 9.0
Square with side 1: Area = 1^2 = 1
Trapezoid with bases 5, 1 and height 9: Area = 0.5 x (5 + 1) x 9 = 27.0</think>
