If the length and width of a rectangle are all integral centimeters, and the area of the rectangle is 24 square centimeters, what is the perimeter of the rectangle?

If the length and width of a rectangle are all integral centimeters, and the area of the rectangle is 24 square centimeters, what is the perimeter of the rectangle?

24 = 1 × 24 = 2 × 12 = 3 × 8 = 4 × 6, so the length and width of a rectangle can be as follows: (1) the length and width are 24 cm and 1 cm respectively, and the perimeter is (24 + 1) × 2 = 50 cm, (2) the length and width are 12 cm and 2 cm respectively, and the perimeter is (12 + 2) × 2 = 28 cm, (3) the length
