Given the following shapes: a right_triangle with base 4 and height 2, a square with side 6, a rectangle with width 8 and height 5, a right_triangle with base 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 4 and height 2: Area = 0.5 x 4 x 2 = 4.0
Square with side 6: Area = 6^2 = 36
Rectangle with width 8 and height 5: Area = 8 x 5 = 40
Right triangle with base 9 and height 1: Area = 0.5 x 9 x 1 = 4.5</think>
