Question

If (x²/a²) + (y²/b²) = 1 is an ellipse, then length of it's latus-rectum is .......

(a) (2b²/a) 

(b) (2a²/b)

(c) depends on whether a > b or b > a

(d) (2a/b²)

Answer 1

The correct option (c) depends on whether a > b or b > a

Explanation:

For ellipse (x²/a²) + (y²/b²) = 1, then length of latus-rectum depends on whether a < b or a > b.
