Answer 2

Answer:

$aea \: of \: equilteral \: triangle = \sqrt{3} \times \frac{ {a}^{2} }{4} \\ a = 16cm \\ = \sqrt{3} \times \frac{ {16}^{2} }{4} \\ = \sqrt{3} \times \frac{16 \times 16}{4} \\ = \sqrt{3} \times \frac{4 \times 16}{1} \\ = 64 \sqrt{3} {cm}^{2}$

$radius \: of \: triangle = median \: of \: tringle = \sqrt{3} \times \frac{a}{2} \\ = \sqrt{3} \times \frac{16}{2} \\ = 32 \sqrt{3} cm \\rads \: of \: triangle = 32 \sqrt{3} cm$
