Question

If area of an equilateral triangle is 16root 3.find perimeter.

Answer 1

area of equilateral triangle is root 3/4 ×a²
a²=64
a=8
perimeter =3*8=24

Answer 2

area of equilateral triangle =. L²(√3)/4
why L is length
and perimeter =3L
According to question
16√3=L²(√3)/4
L²=64
L=8
so, perimeter = 3×8
=24
