Original Khojo Papers practice question — not from a past board paper.
Answer
Eccentricity √7/4 and latus rectum 4.5 units
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
a = 4 and b = 3, so e = √(1 − 9/16) = √7/4 and the latus rectum is 2b2/a = 18/4 = 4.5.
