Given the following shapes: a right_triangle with base 4 and height 1, a right_triangle with base 6 and height 1, a rectangle with width 5 and height 8, a right_triangle with base 1 and height 7. 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
Right triangle with base 6 and height 1: Area = 0.5 x 6 x 1 = 3.0
Rectangle with width 5 and height 8: Area = 5 x 8 = 40
Right triangle with base 1 and height 7: Area = 0.5 x 1 x 7 = 3.5</think>
