Given the following shapes: a right_triangle with base 4 and height 9, a trapezoid with bases 4 and 7 and height 6, a trapezoid with bases 4 and 9 and height 7, a rectangle with width 4 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 4 and height 9: Area = 0.5 x 4 x 9 = 18.0
Trapezoid with bases 4, 7 and height 6: Area = 0.5 x (4 + 7) x 6 = 33.0
Trapezoid with bases 4, 9 and height 7: Area = 0.5 x (4 + 9) x 7 = 45.5
Rectangle with width 4 and height 3: Area = 4 x 3 = 12</think>
