Given the following shapes: a right_triangle with base 3 and height 4, a right_triangle with base 3 and height 8, a rectangle with width 7 and height 1, a trapezoid with bases 6 and 3 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 3 and height 4: Area = 0.5 x 3 x 4 = 6.0
Right triangle with base 3 and height 8: Area = 0.5 x 3 x 8 = 12.0
Rectangle with width 7 and height 1: Area = 7 x 1 = 7
Trapezoid with bases 6, 3 and height 6: Area = 0.5 x (6 + 3) x 6 = 27.0</think>
