Given the following shapes: a right_triangle with base 5 and height 5, a rectangle with width 6 and height 4, a rectangle with width 6 and height 3, a trapezoid with bases 4 and 5 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 5 and height 5: Area = 0.5 x 5 x 5 = 12.5
Rectangle with width 6 and height 4: Area = 6 x 4 = 24
Rectangle with width 6 and height 3: Area = 6 x 3 = 18
Trapezoid with bases 4, 5 and height 4: Area = 0.5 x (4 + 5) x 4 = 18.0</think>
