how to create a area using line geometry in below scenario?

Try the LineExtender prior to the AreaBuilder. I've had some datasets where an Intersector was also needed after the LineExtender. The likely cause is the lines not overlapping given the tolerances in FME. I'm guessing a small extension value will be needed, something like .0001. If you go too large it can produce unwanted results.

Thank you @dustin​  and @danatsafe​ 

That both transformers are creating same result.

But they don't joining the corner ones where other line's endpoints joining. I wish to close remaining 3 sides with highlighted one to create polygon from that.

Is it possible with any transformers?

@saravanakumar​ AreaBuilder should work on it's own as @stefanh​ suggests. Use the Snapping Pre-Processing parameters to set the Snapping Type & Snapping Tolerance.

@saravanakumar​ Many of your lines are not well noded as shown below:

If you use Snapper followed by Intersector, as suggested by others above, that will address most of the problems. But... the line work in the DWG does not close - in some cases there are gaps - in this case about 2m, as shown below:

So these need to be cleaned up with a larger snapper tolerance

Hello @saravanakumar​ ,

I am glad the issue is solved. I couldn't reply earlier, I was outdoors last week.
