Question

The length of each side of an equilateral triangle having an area of 9√3cm square

Answer 1

$area \: of \: equilateral \: triangle \: = \frac{ \sqrt{3} }{4} {x}^{2} \\ so \: \\ \frac{1}{4} {x}^{2} = 9 \\ {x}^{2} = 36 \\ x = \binom{ + }{ - } \sqrt{36} \\ so \: x = + 6 \: ans$
hope this will help you.

Answer 2

Area of an equilateral triangle =√3/4a^2......
√3/4a^2=9√3
a^2=9√3×4/√3
a^2=9×4
a^2=36
a=√36
a=6....



hope it is correct answer
