Given the following shapes: a right_triangle with base 5 and height 8, a right_triangle with base 5 and height 5, a right_triangle with base 8 and height 7, a rectangle with width 3 and height 6. 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 5 and height 5: Area = 0.5 x 5 x 5 = 12.5
Right triangle with base 8 and height 7: Area = 0.5 x 8 x 7 = 28.0
Rectangle with width 3 and height 6: Area = 3 x 6 = 18</think>
