Given the following shapes: a right_triangle with base 9 and height 2, a rectangle with width 2 and height 4, a right_triangle with base 5 and height 5, a rectangle with width 9 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 9 and height 2: Area = 0.5 x 9 x 2 = 9.0
Rectangle with width 2 and height 4: Area = 2 x 4 = 8
Right triangle with base 5 and height 5: Area = 0.5 x 5 x 5 = 12.5
Rectangle with width 9 and height 2: Area = 9 x 2 = 18</think>
