Given the following shapes: a right_triangle with base 8 and height 5, a trapezoid with bases 1 and 7 and height 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 8 and height 5: Area = 0.5 x 8 x 5 = 20.0
Trapezoid with bases 1, 7 and height 7: Area = 0.5 x (1 + 7) x 7 = 28.0</think>
