Given the following shapes: a rectangle with width 8 and height 4, a trapezoid with bases 4 and 6 and height 8, a trapezoid with bases 1 and 4 and height 2, a right_triangle with base 1 and height 8. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 8 and height 4: Area = 8 x 4 = 32
Trapezoid with bases 4, 6 and height 8: Area = 0.5 x (4 + 6) x 8 = 40.0
Trapezoid with bases 1, 4 and height 2: Area = 0.5 x (1 + 4) x 2 = 5.0
Right triangle with base 1 and height 8: Area = 0.5 x 1 x 8 = 4.0</think>
