Infinitely many. Let B be any number less than 6 cm, and let L = 12-B cm. Then the perimeter of the rectangle, with length L and breadth B, is 2*[L+B] = 2*[(12-B)+B] = 2*12 = 24 cm. There are infinitely many possible values for B, between 0 and 6 and so there are infinitely many possible rectangles.
