The general solution to this problem would be starting with prime factoring of the given area:

2160= 2 x 2 x 2 x 2 x 3 x 3 x 3 x 5

From the list of prime factors we can find many combinations, which satisfy the condition: "at least 15":

15 x 144 = 2160

16 x 135 = 2160

18 x 120 = 2160

20 x 108 = 2160

24 x 90 = 2160

27 x 80 = 2160

30 x 72 = 2160

36 x 60 = 2160

45 x 48 = 2160
