engineering mathematics MCQ #401

  1. Question 1

    Q1. The length of the latus rectum of the ellipse x²/25 + y²/16 = 1 is

    • A) 32 / 5
    • B) 25 / 4
    • C) 16 / 5
    • D) 5 / 2

    Answer: 32 / 5

    Explanation: For ellipse x²/a² + y²/b² = 1, length of latus rectum = 2b²/a. Here, a = 5, b = 4, so length = 2*16 / 5 = 32 / 5.
