माना वृत्त \(x ^2-\sqrt{2}( x + y )+ y ^2=0\) के अन्तर्गत त्रिभुज \(A B C\) इस प्रकार है कि \(\angle BAC =\frac{\pi}{2}\) है। यदि भुजा \(AB\) की लम्बाई \(\sqrt{2}\) है, तो \(\triangle ABC\) का क्षेत्रफल है

  1. A \((\sqrt{2}+\sqrt{6}) / 3\)
  2. B \((\sqrt{6}+\sqrt{3}) / 2\)
  3. C \((3+\sqrt{3}) / 4\)
  4. D \(1\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(1\)

Step-by-step Solution

Detailed explanation

Radius of given circle is \(1\) \(BC =\) diameter \(=2, AB =\sqrt{2}\) \(AC =\sqrt{ BC ^{2}- AB ^{2}}=\sqrt{2}\) \(\Delta ABC =\frac{1}{2} AB \cdot AC =1\)
