Getting size of stretched RectTransform ??

How to get size(width and heigth) of stretched rectTransform ?? please help !

Ok, I found out the solution in my case it worked if you need it than try it in your project and give me feedback. This returned me the right size …
rectTransform.rect.width … and rectTransform.rect.heigth …
It worked for me also at stretched RectTransform.

Thank you so much it works for me.

Have you tried multiplying width by localscale.x and height by localscale.y?
