In a

\Delta ABC

\frac{{\left( {a + b + c} \right)\left( {b + c - a} \right)\left( {c + a - b} \right)\left( {a + b - c} \right)}}{{4{b^2}{c^2}}}

equals

View answer and explanation

Correct option: C

{\sin ^2}A

Option C (

{\sin ^2}A

) is correct because the given expression can be simplified using the semi-perimeter formula and trigonometric identities to obtain

{\sin ^2}A
