Given the following shapes: a right_triangle with base 7 and height 8, a trapezoid with bases 5 and 5 and height 1, a right_triangle with base 4 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 8: Area = 0.5 x 7 x 8 = 28.0
Trapezoid with bases 5, 5 and height 1: Area = 0.5 x (5 + 5) x 1 = 5.0
Right triangle with base 4 and height 7: Area = 0.5 x 4 x 7 = 14.0</think>
