Given the following shapes: a right_triangle with base 2 and height 2, a rectangle with width 3 and height 6, a trapezoid with bases 1 and 4 and height 4, 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 2 and height 2: Area = 0.5 x 2 x 2 = 2.0
Rectangle with width 3 and height 6: Area = 3 x 6 = 18
Trapezoid with bases 1, 4 and height 4: Area = 0.5 x (1 + 4) x 4 = 10.0
Rectangle with width 4 and height 3: Area = 4 x 3 = 12</think>
