Given the following shapes: a right_triangle with base 5 and height 4, a trapezoid with bases 7 and 2 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 7, 2 and height 9: Area = 0.5 x (7 + 2) x 9 = 40.5</think>
