Given the following shapes: a right_triangle with base 5 and height 4, a trapezoid with bases 3 and 6 and height 9. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 5 and height 4: Area = 0.5 x 5 x 4 = 10.0
Trapezoid with bases 3, 6 and height 9: Area = 0.5 x (3 + 6) x 9 = 40.5</think>
