Given the following shapes: a trapezoid with bases 6 and 7 and height 1, a square with side 3, a right_triangle with base 3 and height 8. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 6, 7 and height 1: Area = 0.5 x (6 + 7) x 1 = 6.5
Square with side 3: Area = 3^2 = 9
Right triangle with base 3 and height 8: Area = 0.5 x 3 x 8 = 12.0</think>
