Given the following shapes: a square with side 1, a right_triangle with base 1 and height 6, a right_triangle with base 8 and height 1, a rectangle with width 1 and height 5, a rectangle with width 3 and height 5. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Square with side 1: Area = 1^2 = 1
Right triangle with base 1 and height 6: Area = 0.5 x 1 x 6 = 3.0
Right triangle with base 8 and height 1: Area = 0.5 x 8 x 1 = 4.0
Rectangle with width 1 and height 5: Area = 1 x 5 = 5
Rectangle with width 3 and height 5: Area = 3 x 5 = 15</think>
