Answer 2

Answer:

Since, the sum of lengths of any two sides in a triangle should be greater than the length of the third side for the formation of a triangle.

Therefore, the third side should be less than 12+15=27cm.

And also we know that the third side cannot be less than the difference of the two sides.

Therefore, the third side has to be more than 15−12=3cm.

By the above results we can say that the third side should be the length more than 3cm and less than 27cm.

hope it helps you
