Another way to ask this question is, what is the square root of 225? A square root is a number that, when you multiply it by itself, you get the number you started with. For instance, the square root of 4 is 2, because 2x2=4. The square root of 9 is 3, because 3x3=9. We could just keep going and try multiplying different numbers by themselves to see if we get 225, and if you do that, you'd find that 15x15=225. Therefore, the square root of 225 is 15.
144 x 144 = 20,736
3600. (144 * 25) (225 * 16)
1 times 144=144 2 times 72=144 3 times 48=144 4 times 36=144 6 times 24=144 8 times 18=144 9 times 16=144 12 times 12=144
36 x 4 = 144
