Given the following shapes: a trapezoid with bases 4 and 7 and height 6, a square with side 3, a right_triangle with base 2 and height 3, a right_triangle with base 2 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 4, 7 and height 6: Area = 0.5 x (4 + 7) x 6 = 33.0
Square with side 3: Area = 3^2 = 9
Right triangle with base 2 and height 3: Area = 0.5 x 2 x 3 = 3.0
Right triangle with base 2 and height 6: Area = 0.5 x 2 x 6 = 6.0</think>
