Given the following shapes: a right_triangle with base 2 and height 1, a right_triangle with base 6 and height 4, a square with side 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 2 and height 1: Area = 0.5 x 2 x 1 = 1.0
Right triangle with base 6 and height 4: Area = 0.5 x 6 x 4 = 12.0
Square with side 4: Area = 4^2 = 16</think>
