Given the following shapes: a right_triangle with base 4 and height 3, a trapezoid with bases 8 and 4 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 4 and height 3: Area = 0.5 x 4 x 3 = 6.0
Trapezoid with bases 8, 4 and height 2: Area = 0.5 x (8 + 4) x 2 = 12.0</think>
