Given the following shapes: a right_triangle with base 6 and height 7, a rectangle with width 2 and height 6, a rectangle with width 3 and height 9, a rectangle with width 8 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 6 and height 7: Area = 0.5 x 6 x 7 = 21.0
Rectangle with width 2 and height 6: Area = 2 x 6 = 12
Rectangle with width 3 and height 9: Area = 3 x 9 = 27
Rectangle with width 8 and height 3: Area = 8 x 3 = 24</think>
