Given the following shapes: a rectangle with width 5 and height 9, a right_triangle with base 9 and height 1, a trapezoid with bases 4 and 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 9: Area = 5 x 9 = 45
Right triangle with base 9 and height 1: Area = 0.5 x 9 x 1 = 4.5
Trapezoid with bases 4, 7 and height 1: Area = 0.5 x (4 + 7) x 1 = 5.5</think>
