By Pythagoras we have the min limit of third side as
Let the length of third side be L
= 3 cm

and we know the sum of any two sides > the third side so 12 + 15 = 27 cm

so the third side ( L) must lie between

3 < L < 27 cm
Hope it helps
plz mark as best

A triangle  ABC has 3 sides and they have to satisfy the following.

| a - b |  <  c < (a+b)
length of a side must be less the sum of the other two and more than the difference between the other two.

Hence,  the third side,  has to be more than  (15-12) = 3 cm.   Also it has to be less than (15+12) = 27 cm.     It is in between  3 cm and 27 cm.
