Given the following shapes: a right_triangle with base 5 and height 3, a rectangle with width 3 and height 5, a right_triangle with base 2 and height 4, a right_triangle with base 1 and height 8, a right_triangle with base 6 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 5 and height 3: Area = 0.5 x 5 x 3 = 7.5
Rectangle with width 3 and height 5: Area = 3 x 5 = 15
Right triangle with base 2 and height 4: Area = 0.5 x 2 x 4 = 4.0
Right triangle with base 1 and height 8: Area = 0.5 x 1 x 8 = 4.0
Right triangle with base 6 and height 2: Area = 0.5 x 6 x 2 = 6.0</think>
