\triangle A B C, \sin A \sin B+\sin B \sin C+\sin C \sin A=\frac{9}{4}

and

a=2

, then the value of

\sqrt{3} \Delta

, where

\Delta

is area of triangle, is

View answer and explanation

Correct option: A

Option A (3) is correct because the given condition implies that the triangle is equilateral with side 2, and its area multiplied by

\sqrt{3}

is 3.
