Consider a square whose size varies. Let s represent the side length of the square (in cm) and let P represent the perimeter of the square (in cm). a. Write

a formula that expresses P in terms of s. b. Consider the equation 30=4s. i. Solve this equation for s. ii. What does this solution represent? Select all that apply. c. Write a formula that expresses s in terms of P. d. Evaluate your formula from part (c) for P = 30.
