Given the following shapes: a right_triangle with base 5 and height 7, a trapezoid with bases 7 and 6 and height 3, a right_triangle with base 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 5 and height 7: Area = 0.5 x 5 x 7 = 17.5
Trapezoid with bases 7, 6 and height 3: Area = 0.5 x (7 + 6) x 3 = 19.5
Right triangle with base 1 and height 7: Area = 0.5 x 1 x 7 = 3.5</think>
