Question

The equation of directrix and latusrectumof a parabola are 3x-4y+27=0 and 3x - 4y +2=0 then length of latusrectum​

Answer 1

Explanation:

above question is explained in given fig

Answer 2

Answer:

Answer is 10.

Explanation:

Given : 3x-4y+27=0         ..........(equation 1)

           3x-4y+2=0            ..............(equation 2)

To find : length of latus rectum

formula for latus rectum= 4a

let's calculate the value of a

2a= 27-2/$\sqrt{9+16}$ = 25/5 =5

2a will the value of point in graph

means 2a=5

a=5/2

latus rectum length ( according to the above formula)

=4a = 4*5/2

= 2*5

=10.
