Question

Find the length to side of an equilateral triangle having area a root 3 cm square

Answer 1

Let each side of equilateral triangle be 's' cm.

We know that area of the equilateral triangle is equal to (√3 / 4 ) * s²

(√3 / 4 ) * s² = √3

=> s²√3 / 4 = √3

=> s² = √3 * ( 4 / √3 )

=> s² = 4

=> s = √4

=> s = √( 2 * 2 )

=> s = 2 cm

Therefore, L=2
