Answer:

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

Answer:

7 or 12

Step-by-step explanation:

Since we're dealing with a triangle, there are two pairs of sides that are going to be equal to each other.

The left and right would be 7 by 7, and the top and bottom would be 12 by 12.
