What version are you running Maha?

I have 2018 at work so could take a look, but if you're 19 I can't.

Just looking at your equation (I'm reading between the lines here) it could be possible that you could delete it and use an equal relation instead

Is that the intent?

A little tip that might help

When using equations instead of trying to achieve it all in one sketch, break it up into two.

Then make sure that the equations are in the second sketch and they refer to dimensions in the first.

I think it is possible to make it work in 1 sketch (and after all you are only getting a warning) , but splitting it up into two will guarantee that there is no circular reference.

An equation is showing over defined. How to fix it?

It is not overdefined, it is simply a warning. If you hover over the warning icon it says "Potential circular reference". Then if you hover over the yellow "Arc Length@Sketch4" text in the right hand side of the equation, it tells you what terms of the equation are potentially circular. If your equation was longer, you'd see that it only highlights the terms in yellow that contribute to the potential circular reference.

The reason why it is potentially a circular reference is because the term on the right hand side of the equation is a reference dimension, not a driving dimension, and referencing those can cause circular references. It is a valid approach to designing so SOLIDWORKS does not block it completely, but the warning is just so the user is aware of the potential issue. If the design of the sketch is such that you know it won't cause a circular reference, you can just ignore the warning.I hope it helps,

In Solidworks help there is a drop down that allows you to select the version.

If you use it you can tell when things changed. Give it a try
