The formula for the area of a square is area = (side)2. Factor 9x2 + 6x + 1 to find the side length of the sheet. Write a formula for the perimeter of the sheet, and evaluate the expression for x = 3. 3 Solve 9x2 + 6x + 1 = (3x + 1)2 The side length is (3x + 1) m P = 4s = 4(3x + 1) = 12x + 4 When x = 3 m, the perimeter is 12(3) + 4 = 36 + 4 = 40 m 4 Look Back For a square with a perimeter of 40
