Given the following shapes: a right_triangle with base 2 and height 4, a rectangle with width 7 and height 6, a trapezoid with bases 9 and 5 and height 4, a trapezoid with bases 9 and 6 and height 1, a square with side 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 2 and height 4: Area = 0.5 x 2 x 4 = 4.0
Rectangle with width 7 and height 6: Area = 7 x 6 = 42
Trapezoid with bases 9, 5 and height 4: Area = 0.5 x (9 + 5) x 4 = 28.0
Trapezoid with bases 9, 6 and height 1: Area = 0.5 x (9 + 6) x 1 = 7.5
Square with side 1: Area = 1^2 = 1</think>
