Given the following shapes: a right_triangle with base 3 and height 8, a right_triangle with base 7 and height 7, a right_triangle with base 6 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 3 and height 8: Area = 0.5 x 3 x 8 = 12.0
Right triangle with base 7 and height 7: Area = 0.5 x 7 x 7 = 24.5
Right triangle with base 6 and height 1: Area = 0.5 x 6 x 1 = 3.0</think>
