\mathfrak{\bf{\underline{\underline{Fᴏʀᴍᴜʟᴀ \ ⟹}}}}

⟹ㅤㅤㅤArea \: of \: E quilateral \: Triangle \:  =  \frac{ \sqrt{3} }{4}  {a}^{2}  \\

⟹ㅤㅤㅤArea \: of  \: Triangle \: =  \frac{1}{2}  \:  \times b \: \times   {h}

ㅤㅤArea \: of \: E quilateral \: Triangle \: = 8 \sqrt{3}

ㅤㅤㅤㅤㅤㅤㅤ \frac{ \sqrt{3} }{4}  {a}^{2}  = 8 \sqrt{3 }  \\ㅤㅤㅤㅤㅤㅤ  {a }^{2}  = 8 \times 4 \\  ㅤㅤㅤㅤㅤㅤ{a}^{2}  = 32 \\ㅤㅤㅤㅤㅤㅤ a =  \sqrt{32}  \\ ㅤㅤㅤㅤㅤㅤㅤa = 4 \sqrt{2}
