Answer:
Step-by-step explanation: One important property of a square is that all the sides of the square have the same length. That means, if a square has a perimeter of P, then one side must have a length of P/4 units. So for a square with a perimeter of (12x + 52) units, its sides would have a length of (12x + 52)/4 = (3x + 13) units. Therefore, the answer is C: (3x + 13) units.
