A pair of tangents OA,OB (O is origin) is drawn to a circle whose cent – InterviewSolution

1.	A pair of tangents OA,OB (O is origin) is drawn to a circle whose centre is C and radius is 3 units. If the combined equation of OA and OB is 2x2−3xy+y2=0, then the area (in sq. units) of the quadrilateral OACB is equal to
Answer» A pair of tangents $O A, O B$ $(O$ is origin $)$ is drawn to a circle whose centre is $C$ and radius is $3$ units. If the combined equation of $O A$ and $O B$ is $2 x^{2} - 3 x y + y^{2} = 0,$ then the area (in sq. units) of the quadrilateral $O A C B$ is equal to
