In any Δ   ABC,    b2  sin⁡  2  C+c2  sin⁡  2  B\Delta \,\;ABC,\,\,\;{b^2}\,\,\sin \,\,2\;C + {c^2}\,\,\sin \,\,2\;B

View answer and explanation
Correct option: D
4  Δ4\;\Delta
Option D (4  Δ4\;\Delta) is correct because it is the simplified form of the expression after applying the sine rule and the area formula of a triangle.
