Given the following shapes: a right_triangle with base 5 and height 8, a right_triangle with base 4 and height 9, a trapezoid with bases 4 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 5 and height 8: Area = 0.5 x 5 x 8 = 20.0
Right triangle with base 4 and height 9: Area = 0.5 x 4 x 9 = 18.0
Trapezoid with bases 4, 1 and height 7: Area = 0.5 x (4 + 1) x 7 = 17.5</think>
