The Latusrectum of an ellipse is 10 and the eccentricity is `(2)/(3)`then length of major axis

The Latusrectum of an ellipse is 10 and the eccentricity is (2)/(3) then (1) major axis is 18 (2) minor axis is 6sqrt(5) (3) distance between foci is 12 (4) distance between extremities of major axis and minor axis is 6sqrt(14)

The length of the latusrectum of an ellipse is (18)/(5) and eccentricity is (4)/(5) , then equation of the ellipse is . .

In an ellipse length of minor axis is 8 and eccentricity is (sqrt(5))/(3) . The length of major axis is

The distanve between the foci of an ellipse is 16 and eccentricity is 1/2. Length of the major axis of the cellipse is

A focus of an ellipse is at the origin.The directrix is the line x=4 and the eccentricity is (1)/(2) Then the length of the semi-major axis is

If x^2/(sec^2 theta) +y^2/(tan^2 theta)=1 represents an ellipse with eccentricity e and length of the major axis l then
