9. What is the relationship between the perimeter of a square and the measurement of its length? a. The perimeter of a square depends upon the length of its side. b. The perimeter of a square depends upon the square of its side. C. The perimeter of a square is equal to its side. d. The length of the side of a square depends on its perimeter.
Since all sides of a square are equal, we only need one side to find its perimeter. The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
