Given the following shapes: a right_triangle with base 1 and height 4, a trapezoid with bases 8 and 2 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 1 and height 4: Area = 0.5 x 1 x 4 = 2.0
Trapezoid with bases 8, 2 and height 2: Area = 0.5 x (8 + 2) x 2 = 10.0</think>
