If the eccentricity of an ellipse is `5/8` and the distance between the foci is 10, then find the length of latus rectum of the ellipse.

Find the eccentricity of the ellipse if : the distance between the foci is equal to the length of latus-rectum.

Find the length of latus rectum of the ellipse. x^2/16+y^2/9=1 .

The eccentricity of the ellipse, if the minor axis is equal to the distance between the foci is:

Find the length of latus rectum of the ellipse x^(2)/25+y^(2)/16=1 .

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

If, in a hyperbola, the distance between the foci is 10 and the transverse axis has length 8, then the length of its latus-rectum is:

The latus rectum of the ellipse 16x^2+y^2=16 is:

In the following, find the coordinates of the foci, the vertices, the length of major axis, the minor axis, the eccentricity and the length of the latus rectum of the ellipse. x^2/36+y^2/16=1

In the following, find the coordinates of the foci, the vertices, the length of major axis, the minor axis, the eccentricity and the length of the latus rectum of the ellipse. x^2/4+y^2/25=1
