Given the following shapes: a right_triangle with base 7 and height 6, a right_triangle with base 9 and height 9, a trapezoid with bases 1 and 1 and height 1, a rectangle with width 9 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 7 and height 6: Area = 0.5 x 7 x 6 = 21.0
Right triangle with base 9 and height 9: Area = 0.5 x 9 x 9 = 40.5
Trapezoid with bases 1, 1 and height 1: Area = 0.5 x (1 + 1) x 1 = 1.0
Rectangle with width 9 and height 1: Area = 9 x 1 = 9</think>
