Questions
detailed solution
Correct option is B
x2−2y2−22x−42y−6=0 or x2−22+2−2y2+22y+2=4 or (x−2)24−(y+2)22=1Now B is one of the end points of its latus rectum and C is the focus of the hyperbola nearest to the vertex A. Clearly, area of LABC does not change if we consider similar hyperbola with center at (0,0) or hyperbola x24−y22=1 Here vertex is A(2,0) . ∴ a2e2=a2+b2=6 So, one of the foci is B(6,0) , point C is ae,b2/a or (6,1) . ∴ AB=6−2 and BC=1∴ Area of ΔABC=12AB×BC=12(6−2)×1 =32−1 sq.units.Talk to our academic expert!
