Given the following shapes: a right_triangle with base 2 and height 3, a rectangle with width 4 and height 7, a right_triangle with base 7 and height 8, a right_triangle with base 8 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 2 and height 3: Area = 0.5 x 2 x 3 = 3.0
Rectangle with width 4 and height 7: Area = 4 x 7 = 28
Right triangle with base 7 and height 8: Area = 0.5 x 7 x 8 = 28.0
Right triangle with base 8 and height 1: Area = 0.5 x 8 x 1 = 4.0</think>
