Heya Sista....

Your question :-
#Area of the quadrilateral triangle in 64 root 3 cm 2 find the length of the side.

This is your answer....

It is given that area of equilateral triangle is 64√3 cm². 
We have to find the length.

We know that the area of equilateral triangle is  \frac{ \sqrt{3} }{4}  l^{2} where l is the side of triangle.

So by using this formula.

[tex]-\ \textgreater \ 64 \sqrt{3} = \frac{ \sqrt{3} }{4} l^{2} \\ -\ \textgreater \ 64 X 4 = l^{2} \\ -\ \textgreater \ l^{2} = 256 \\ -\ \textgreater \ l=16. [/tex]

Hence, the length of side is 16 cm.

Hope it helps you all....

Hii !!!

This is Your answer...

Area of equilateral triangle, A = √3/4 X a².   (a = length of side).
Area = 64√3 cm².
So, 
√3/4 X a² = 64√3 
a² = 64 X 4
a = √64 X √4
a = 8 X 2 
a - 16.

Hence, the side of equilateral triangle is 16cm.

Hope it helps
