HEYA.....!!!
Your answer ⏬⏬
Area of an equilateral triangle =2√3 cm²
=> √³/4 a² =2/√3
=> a²=2/√3 x 4/√3
=>a²=8/3
=>a= √8/3
and we know that all sides in equaliteral triangle are equal.
Semi perimeter = a+b+c /2
=>√8/3+√8/3+√8/3 /2
=>2.8284/2
=>1.4142 cm

As the area of equilateral triangle = side^2 *(root3/4)
here, 2root3 = side^2 (root3/4)
root3 will cancel,
2=side^2/4
2*4 = side^2
8=side^2
root8 = side
the perimeter of equilateral triangle =3*side
= 3*root8
=2*3 root2
=6root2
i hope this will help you
