उत्तर
Area of an equilateral triangle say A, having each side a cm is given by
`A = sqrt(3)/4 a^2`
We are asked to find the side of the triangle
Therefore, the side of the equilateral triangle says a, having area ` 4 sqrt(3) cm^2` is given by
`4sqrt(3 ) = sqrt(3)/4 a^2`
`a^2 = (4sqrt(3) xx 4)/sqrt(3) `
a2 = 16
a = `sqrt(16)`
a = 4 cm
