Given the following shapes: a square with side 3, a trapezoid with bases 5 and 5 and height 4, a right_triangle with base 5 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Square with side 3: Area = 3^2 = 9
Trapezoid with bases 5, 5 and height 4: Area = 0.5 x (5 + 5) x 4 = 20.0
Right triangle with base 5 and height 4: Area = 0.5 x 5 x 4 = 10.0</think>
