Answer 1

Its 3√3
Area =√3/4 side sq.
=√3/4 into 2√3 whole sq.
=3√3

Answer 2

area of an equilateral triangle =
$\frac{ \sqrt{3} }{4} \times {side}^{2} \\ \frac{ \sqrt{3} }{4} \times {(2 \sqrt{3}) }^{2} \\ \frac{ \sqrt{3} }{4} \times 4 \times 3 \\ 3 \sqrt{3} {cm}^{2}$
the area of the given equilateral triangle is 3√3cm square
