Given the following shapes: a rectangle with width 5 and height 5, a right_triangle with base 9 and height 2, a square with side 2, a right_triangle with base 7 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 5 and height 5: Area = 5 x 5 = 25
Right triangle with base 9 and height 2: Area = 0.5 x 9 x 2 = 9.0
Square with side 2: Area = 2^2 = 4
Right triangle with base 7 and height 1: Area = 0.5 x 7 x 1 = 3.5</think>
