Given the following shapes: a right_triangle with base 3 and height 2, a right_triangle with base 3 and height 5, a rectangle with width 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 3 and height 2: Area = 0.5 x 3 x 2 = 3.0
Right triangle with base 3 and height 5: Area = 0.5 x 3 x 5 = 7.5
Rectangle with width 1 and height 9: Area = 1 x 9 = 9</think>
