Given the following shapes: a rectangle with width 4 and height 1, a rectangle with width 8 and height 5, a right_triangle with base 7 and height 1, a right_triangle with base 5 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 4 and height 1: Area = 4 x 1 = 4
Rectangle with width 8 and height 5: Area = 8 x 5 = 40
Right triangle with base 7 and height 1: Area = 0.5 x 7 x 1 = 3.5
Right triangle with base 5 and height 4: Area = 0.5 x 5 x 4 = 10.0</think>
