Given the following shapes: a right_triangle with base 6 and height 9, a right_triangle with base 9 and height 4, a rectangle with width 6 and height 7, a right_triangle with base 1 and height 8. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 6 and height 9: Area = 0.5 x 6 x 9 = 27.0
Right triangle with base 9 and height 4: Area = 0.5 x 9 x 4 = 18.0
Rectangle with width 6 and height 7: Area = 6 x 7 = 42
Right triangle with base 1 and height 8: Area = 0.5 x 1 x 8 = 4.0</think>
