Question

The length of each side of an equilateral triangle having an area of 9√3 cm2 using Heron's formula is?

Answer 1

Answer:

The area of equilateral triangle is 93cm2

 

Since, the area of equilateral triangle is

=43a2

 

Therefore,

43a2=93

a2=9×4

a2=36

a=6cm

 

Hence, the side of the triangle is 6cm
