Correct Answer - Option 1 : 16
Concept:
Parabola:
The length of latus rectum of the parabola y2 = 4ax is given by: 4a
Calculation:
Given: y2 = 16x
The given equation can be written as, y2 = 4 ⋅ 4 ⋅ x
By comparing the above equation with the standard equation of the parabola, y2 = 4ax we get
⇒ a = 4
As we know that, length of latus rectum of the parabola y2 = 4ax is given by: 4a
⇒ 4a = 16
Hence, the correct option is 1.
