Question

. Find the area of the triangle formed by
the straight lines 2x-y-5=0, x-5y+11=0
and x + y - 1 = 0.​

Answer 1

Step-by-step explanation:

Find the area of the triangle formed by the straight lines x-sy+ll = 0 and x+y-1= 0.

Sol.

Given lines

2x-y-530..................(1)

x-sy+11-0 x+y-130.........(2)

2x - y - 5 = 0............(3)

SOLVING (I) and (2), vertex A = (4, 3) By solving (2), (3) vertex B = (-1, 2) By solving (3), (1) vertex c= (2,-1)
