Perimeter of large triangle P = L + L + L = 63
but you know two sides so  P = 18 + 18 + L  = 63

and so your last side is 27

anonymous · Answer

dilations deal with how big one side is to the other so your dilation factor here is 3

How did you get 3? I just want to make sure.. @JAMG

6 * 3 = 18

6 * 3 = 18

s * 3 = 27
