Question

If the area of an
equilateral triangle is 16√3 sq. cm, then find the perimeter of the triangle​

Answer 1

Answer:

Step-by-step explanation:

Area of an equilateral triangle

=  \frac{ \sqrt{3} }{4}  {a}^{2}  

where 'a' is side of equilateral triangle

So

\frac{ \sqrt{3} }{4}  {a}^{2}  = 16 \sqrt{3}  

\frac{ {a}^{2} }{4}  = 16

{a}^{2}  = 4 \times 16

{a}^{2}   = 64

a =  \sqrt{64}  

a=8cm

perimeter =3(8)

=24cm
