Given the following shapes: a right_triangle with base 3 and height 5, a right_triangle with base 4 and height 3, a rectangle with width 4 and height 5, a trapezoid with bases 8 and 4 and height 5, a right_triangle with base 8 and height 5. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 3 and height 5: Area = 0.5 x 3 x 5 = 7.5
Right triangle with base 4 and height 3: Area = 0.5 x 4 x 3 = 6.0
Rectangle with width 4 and height 5: Area = 4 x 5 = 20
Trapezoid with bases 8, 4 and height 5: Area = 0.5 x (8 + 4) x 5 = 30.0
Right triangle with base 8 and height 5: Area = 0.5 x 8 x 5 = 20.0</think>
