JEE Math Practice Question
Let the line x+y=1 meet the circle $x^2+y^2=4$ at the points A and B. If the line perpendicular to AB and passing through the mid-point of the chord AB intersects the circle at C and D, then the area of the quadrilateral ABCD is equal to :
- A.$ \sqrt{14} $
- B.$ 3\sqrt{7} $
- C.$ 2\sqrt{14} $
- D.$ 5\sqrt{7} $
