Question

the area of an equilateral triangle is 9√3 sq. cm. find its each side​

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

The length of each side of an equilateral triangle having an area of 9√3cm2is. Hence, the length of an equilateral triangle is 6cm.

Answer 2

Answer:

6 cm

Step-by-step explanation:

The area of equilateral triangle is 9root3 cm sq.

Since the area of equilateral triangle is root3/4 a sq.

Therefore root 3/4 a sq. = 9 root 3

a sq. = 9*4

a sq. =36

a=6

Hence the side is 6 cm
