Length of the latus rectum of an ellipse

In Q.(13) length of the latus rectum of the ellipse is

The length of the latus rectum of the ellipse 3x^(2) + y^(2) = 12 is …….

If the length of the eccentricity of an ellipse is (3)/(8) and the distance between the foci is 6 units, then the length of the latus rectum of the ellipse is

If the length of the eccentricity of an ellipse is (3)/(8) and the distance between the foci is 6 units, then the length of the latus rectum of the ellipse is

Length of the latus rectum of the ellipse (x^(2))/(25)+(y^(2))/(9)=1 is

find the length of the latus rectum of the ellipse (x^(2))/(9) +(y^(2))/(16) = 1

The length of the latus rectum of the ellipse 5x ^(2) + 9y^(2) =45 is

The length of the latus rectum of the ellipse 2x^(2) + 3y^(2) - 4x - 6y - 13 = 0 is
