Circles

Ans.(4)

@100miles
Tangents are perpendicular to radius.
So the tangents, the radius, and the line joining the given point and centre of circle form a right angled triangle.Length of tangent from external point sud be root S1.
And uk the radius from the eqn.
So now you can get the third side of the triangle. And then apply
Half.Base.Height accordingly.
Area of both triangles together is area of quadrilateral
