if ellipse is sliding down along the coordinate axes, then origin will lie on the director circle of ellipse. take center of ellipse as (h,k) and write the equation of its director circle. then satisfy origin in the equation. you will get the locus of center of ellipse. then using integration. find the length of the arc made by center of ellipse.
