Given the following shapes: a right_triangle with base 3 and height 7, a square with side 2, a right_triangle with base 2 and height 9, a square with side 2, a trapezoid with bases 5 and 1 and height 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 3 and height 7: Area = 0.5 x 3 x 7 = 10.5
Square with side 2: Area = 2^2 = 4
Right triangle with base 2 and height 9: Area = 0.5 x 2 x 9 = 9.0
Square with side 2: Area = 2^2 = 4
Trapezoid with bases 5, 1 and height 7: Area = 0.5 x (5 + 1) x 7 = 21.0</think>
