comment Foci of Ellipse - given: Width and Height
If ellipse and rectangle have four contact points: translate and maybe rotate an ellipse to situate its center in $(0,0)$, and then $a = p / 2$, $b = s / 2$ (or vice versa). If you need positions of foci as vectors, make inverse translation and rotation. If there are less than four contact points, there are infinity of solutions.
