Given the following shapes: a trapezoid with bases 3 and 4 and height 4, a trapezoid with bases 4 and 6 and height 2, a trapezoid with bases 7 and 5 and height 3, a right_triangle with base 8 and height 1, a rectangle with width 4 and height 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 3, 4 and height 4: Area = 0.5 x (3 + 4) x 4 = 14.0
Trapezoid with bases 4, 6 and height 2: Area = 0.5 x (4 + 6) x 2 = 10.0
Trapezoid with bases 7, 5 and height 3: Area = 0.5 x (7 + 5) x 3 = 18.0
Right triangle with base 8 and height 1: Area = 0.5 x 8 x 1 = 4.0
Rectangle with width 4 and height 7: Area = 4 x 7 = 28</think>
