Given the following shapes: a right_triangle with base 8 and height 2, a rectangle with width 3 and height 3, a rectangle with width 1 and height 6, a right_triangle with base 2 and height 5. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 8 and height 2: Area = 0.5 x 8 x 2 = 8.0
Rectangle with width 3 and height 3: Area = 3 x 3 = 9
Rectangle with width 1 and height 6: Area = 1 x 6 = 6
Right triangle with base 2 and height 5: Area = 0.5 x 2 x 5 = 5.0</think>
