Given the following shapes: a rectangle with width 4 and height 8, a right_triangle with base 7 and height 5, a right_triangle with base 2 and height 3, a right_triangle with base 4 and height 9. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 4 and height 8: Area = 4 x 8 = 32
Right triangle with base 7 and height 5: Area = 0.5 x 7 x 5 = 17.5
Right triangle with base 2 and height 3: Area = 0.5 x 2 x 3 = 3.0
Right triangle with base 4 and height 9: Area = 0.5 x 4 x 9 = 18.0</think>
