Given the following shapes: a trapezoid with bases 7 and 8 and height 3, a trapezoid with bases 5 and 4 and height 2, a rectangle with width 1 and height 4, a trapezoid with bases 3 and 6 and height 5, a right_triangle with base 5 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 7, 8 and height 3: Area = 0.5 x (7 + 8) x 3 = 22.5
Trapezoid with bases 5, 4 and height 2: Area = 0.5 x (5 + 4) x 2 = 9.0
Rectangle with width 1 and height 4: Area = 1 x 4 = 4
Trapezoid with bases 3, 6 and height 5: Area = 0.5 x (3 + 6) x 5 = 22.5
Right triangle with base 5 and height 6: Area = 0.5 x 5 x 6 = 15.0</think>
