Given the following shapes: a right_triangle with base 2 and height 4, a right_triangle with base 2 and height 6, a square with side 4, a square with side 3, a square with side 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 2 and height 4: Area = 0.5 x 2 x 4 = 4.0
Right triangle with base 2 and height 6: Area = 0.5 x 2 x 6 = 6.0
Square with side 4: Area = 4^2 = 16
Square with side 3: Area = 3^2 = 9
Square with side 2: Area = 2^2 = 4</think>
