d
0
detailed solution
Correct option is B
Split the given equation 2x2-5xy+2y2=0 as 2x-y=0 and x-2y=0General points on both lines are l,2l,2m,mHence, the vertices of the triangle are 0,0,l,2l,2m,m is l+2m3,2l+m3=2,3Equate corresponding co - ordinates and then solve for L , M We get l=4,m=1The vertices of triangle are (0, 0), (4, 8), (2, 1)The area of the triangle formed by the above vertices is 12|(4−16)|=6 square unitsTalk to our academic expert!
