Given the following shapes: a right_triangle with base 4 and height 1, a rectangle with width 5 and height 4, a right_triangle with base 8 and height 1, a right_triangle with base 2 and height 2, a rectangle with width 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 4 and height 1: Area = 0.5 x 4 x 1 = 2.0
Rectangle with width 5 and height 4: Area = 5 x 4 = 20
Right triangle with base 8 and height 1: Area = 0.5 x 8 x 1 = 4.0
Right triangle with base 2 and height 2: Area = 0.5 x 2 x 2 = 2.0
Rectangle with width 2 and height 5: Area = 2 x 5 = 10</think>
