Given the following shapes: a rectangle with width 7 and height 4, a trapezoid with bases 6 and 2 and height 2, a right_triangle with base 1 and height 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 7 and height 4: Area = 7 x 4 = 28
Trapezoid with bases 6, 2 and height 2: Area = 0.5 x (6 + 2) x 2 = 8.0
Right triangle with base 1 and height 7: Area = 0.5 x 1 x 7 = 3.5</think>
