    The length of third side is 15.

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The perimeter of given triangle is 44.

One side, suppose a is 18.

Second side, suppose b is 11.

Suppose, third side is c.

So the perimeter will be :

Subtracting 29 in both sides

Hence the length of third side is 15.       Answer
