Question

find the length of each side of an equilateral triangle having area of 9 root 3 cm square

Answer 1

Answer:

6cm

Step-by-step explanation:

Area=$9\sqrt{3}$ $cm^{2}$

Let side=a cm

As we know Area Of Equilateral triangle=

so $\sqrt{3} /4 a^{2}$=9$\sqrt{3}$

$a^{2}$ =36

a=6 cm

Answer 2

Given that,

Area of an equilateral triangle is, $A=9\sqrt3\ cm$

To find,

The length of each side of triangle.

Solution,

Area of an equilateral triangle is given by the formula as follows :

$A=\dfrac{\sqrt{3} }{4}a^2$

a is length of each side

$9\sqrt3=\dfrac{\sqrt{3} }{4}a^2\\\\a^2=36\\\\a=6\ cm$

So, the length of each side is 6 cm.
