How would i do this question?(adsbygoogle = window.adsbygoogle || []).push({});

A canal with cross-section a semi-ellipse of width 20 m is 5 m deep at the centre. Find the equation for the ellipse, and use it to find the depth 2 m from the edge.

I think i have a way to get it using major axis length 20 and minor axis length 10, but what would the specific points be (where is the centre?) thanks.
