Given the following shapes: a rectangle with width 1 and height 4, a trapezoid with bases 5 and 4 and height 6, a right_triangle with base 8 and height 2, a right_triangle with base 7 and height 5. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 1 and height 4: Area = 1 x 4 = 4
Trapezoid with bases 5, 4 and height 6: Area = 0.5 x (5 + 4) x 6 = 27.0
Right triangle with base 8 and height 2: Area = 0.5 x 8 x 2 = 8.0
Right triangle with base 7 and height 5: Area = 0.5 x 7 x 5 = 17.5</think>
