area = √3/4a²
√3/4a² = 4/√3
a² = 16/3
a = 4/√3
√3/4a² = 4/√3
a² = 16/3
a = 4/√3

Area of equilateral triangle = 1/4*a*(3)^1/2a
= [(3)^1/2* a*a] /4
Here a is the side of the triangle,
Putting area value in the above formula,
(root 3)* a*a /4 = 4 root 3
=> a*a = 4*4
Thus a = 4
= [(3)^1/2* a*a] /4
Here a is the side of the triangle,
Putting area value in the above formula,
(root 3)* a*a /4 = 4 root 3
=> a*a = 4*4
Thus a = 4
