Answer 1

l think it's help you please mark me as brainiest

Answer 2

Hey MATE!

Area of equilateral triangle is :

$\frac{ \sqrt{3} \: {a}^{2} }{4}$
where 'a' is length of each side.

Therefore,

$64 \sqrt{3} = \frac{ \sqrt{3} \: {a}^{2} }{4} \\ \\ 64 \times 4 = {a}^{2} \\ \\ a = \sqrt{256} \\ \\ a = 16 \: cm$
Hope it helps
