Given the following shapes: a right_triangle with base 7 and height 2, a square with side 5, a trapezoid with bases 3 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 7 and height 2: Area = 0.5 x 7 x 2 = 7.0
Square with side 5: Area = 5^2 = 25
Trapezoid with bases 3, 1 and height 7: Area = 0.5 x (3 + 1) x 7 = 14.0</think>
