Answer:
The latus rectum of a conic section is the chord through a focus parallel to the conic section directrix (Coxeter 1969). "Latus rectum" is a compound of the Latin latus, meaning "side," and rectum, meaning "straight." Half the latus rectum is called the semilatus rectum.
Explanation:
Find the length of the latus rectum whose parabola equation is given as, y2 = 12x. Hence, the length of the latus rectum of a parabola is = 4a = 4(3) =12.
