Answer :

Given the equation of the ellipse is 4x^{2} + 9y^{2} = 1.

We need to find the eccentricity, coordinates of foci and length of latus rectum.

Given equation can be rewritten as .

We know for the ellipse (a^{2}>b^{2})

⇒

⇒ Coordinates of foci (±ae,0)

⇒ Length of latus rectum =

Here and , a^{2}>b^{2}

⇒

⇒

⇒

⇒

⇒

⇒

⇒ Length of latus rectum (L) =

⇒

∴ The eccentricity is , foci are and length of the latus rectum is .
