Answer 2

Answer:

$We \: know \: that, the \: area \: of \\ equilateral \: triangle \: is \: given \: by  \\ a = \frac{3}{4} {a}^{2}</p><p>, where a is \: side \: of triangle \\ We \: are \: given \: that \: area \: of \\ equilateral \: triangle \: is \\ a = 25 \sqrt{3} \: m² \\ so =25 \sqrt{3} = \frac{3}{4} {a}^{2} \\ {a}^{2} = \frac{ 25\sqrt{3} \times 4}{ \sqrt{3} } = 100 \\ a = 10 \: m$
