Given the following shapes: a right_triangle with base 1 and height 5, a rectangle with width 4 and height 2, a square with side 6, a trapezoid with bases 2 and 2 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 1 and height 5: Area = 0.5 x 1 x 5 = 2.5
Rectangle with width 4 and height 2: Area = 4 x 2 = 8
Square with side 6: Area = 6^2 = 36
Trapezoid with bases 2, 2 and height 2: Area = 0.5 x (2 + 2) x 2 = 4.0</think>
