If an isosceles triangle the length of each equal side is 'a' units and that of the third side is 'b' units, then its area will be :

A

`a/2 sqrt(2a^2-b^2)` sq.units/ वर्ग इकाई

B

`b/2 sqrt(a^2-2b^2)` sq.units/ वर्ग इकाई

C

`a/4 sqrt(4b^2-a^2)` sq.units/ वर्ग इकाई

D

`b/4 sqrt(4a^2-b^2)` sq.units/ वर्ग इकाई
