The perimeter is all the side lengths added up.
Add up all the side lengths:
6x - 4 + 6x - 4 + 12x + 3 + 12x + 3 + 14x + 13
Add all like terms.
50x + 11

The answer is C) 50x + 11 units
To find the perimeter add all sides.

the two sides of the top are congruent because they both are marked by one line.

the two sides of the square are congruent because they both are marked by two lines.

6x - 4 + 6x - 4 + 12x + 3 + 12x + 3 + 14x + 13 
50x + 11 

The answer is C

Hope this helps :)
