Given the following shapes: a right_triangle with base 3 and height 7, a square with side 5, a trapezoid with bases 9 and 2 and height 7, a right_triangle with base 2 and height 4. 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 5: Area = 5^2 = 25
Trapezoid with bases 9, 2 and height 7: Area = 0.5 x (9 + 2) x 7 = 38.5
Right triangle with base 2 and height 4: Area = 0.5 x 2 x 4 = 4.0</think>
