For the ellipse , the latus rectum is

 1
 2
 4
Hint:
Latus rectum of ellipse is the focal chord that is perpendicular to the axis of the ellipse. The ellipse has two focus and hence there are two latus rectum for an ellipse. The length of the latus rectum of the ellipse having the standard equation of
is
The correct answer is: 1
Latus rectum of ellipse is the focal chord that is perpendicular to the axis of the ellipse. The ellipse has two focus and hence there are two latus rectum for an ellipse. The length of the latus rectum of the ellipse having the standard equation of
is
Given :
Length of latus rectum = =
Thus, for the ellipse , the latus rectum is 1.
