Question

using heron formula find the area of an equilateral triangle the lengths of whose one side is.​

Answer 1

Answer:

let the side of equilateral triangle be x

now according to herons formula

s=x+x+x/2=3x/2

S=√S(s-a) (s-b) (s-c)

S=√3x/2(3x/2-x) (3x/2-x) (3x-x)

s=√3x/2×x/2×x/2×x/2

s=√3/4x^2
