One side of a square is 3x + 2. Which expression represents the perimeter? A) 2 (3x + 2) B) (3x + 2) ². C) 4 (3x + 2).

The correct answer to this question is letter "C. 4 (3x + 2)."

A) 2 (3x + 2), this shows the total length of the two sides of a square

B) (3x + 2) ², this shows the area of the square

C) 4 (3x + 2), this shows the perimeter of a square.
