The answer would be the top answer in the left corner. (The side length*4) because a square has four sides, and the perimeter is adding up ALL sides, so it would be adding up four total sides.
OK.... I believe the answer you would be looking for would explain what the perimeter would be. The perimeter is the side lengths times 4 That would be 19/2 So your answer would be Answer A or Perimeter times 4
