Given the following shapes: a right_triangle with base 8 and height 5, a trapezoid with bases 2 and 1 and height 8, a square with side 1, a trapezoid with bases 3 and 4 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 8 and height 5: Area = 0.5 x 8 x 5 = 20.0
Trapezoid with bases 2, 1 and height 8: Area = 0.5 x (2 + 1) x 8 = 12.0
Square with side 1: Area = 1^2 = 1
Trapezoid with bases 3, 4 and height 4: Area = 0.5 x (3 + 4) x 4 = 14.0</think>
