Given the following shapes: a right_triangle with base 6 and height 2, a trapezoid with bases 3 and 6 and height 5, a square with side 4, a trapezoid with bases 2 and 9 and height 5. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 6 and height 2: Area = 0.5 x 6 x 2 = 6.0
Trapezoid with bases 3, 6 and height 5: Area = 0.5 x (3 + 6) x 5 = 22.5
Square with side 4: Area = 4^2 = 16
Trapezoid with bases 2, 9 and height 5: Area = 0.5 x (2 + 9) x 5 = 27.5</think>
