In the ellipse distance between the foci is equal to the distance between a focus and one end of minor axis then its eccentricity is

In an ellipse,the distances between its foci is 6 and minor axis is 8. Then its eccentricity is

If the distance between the foci of an ellipse is equal to length of minor axis, then its eccentricity is

In an ellipse the distance between the foci is 8 and the distance between the directrices is 25. The length of major axis, is

If the distance between the directrices is thrice the distance between the foci, then find eccentricity of the ellipse.

Can the distance between foci of an ellipse be equal to distance its directrices ?

In an ellipse the distance between the foci is 8 and the distance between the directrices is 25, then the ratio of the length of major and minor axis is

If m times distance between foci of an ellipse is equal to n times distance between its directrices , then
