Solution :-
Points :-
A (2, 3), B( 4, k) and C( 6 - 3 )
To prove they are collinear.
Apply staircase Method and equate to zero.
| 2 3 |
| 4 K | × 1/2 = 0
| 6 -3 |
| 2 3 |
= [2k - 3(4) -4(3) - 6(k) + 6(3) -(-3)(2)] ×1/2 = 0
[ 2k -12 -12-6k+18+6] × 1/2 = 0
[-4k ] = 0
K = 0 /-4
k = 0

Given that A, B and C are collinear
Hence ar(DABC) = 0
Hence ar(DABC) = 0
