Question

Area of an equilateral triangle is 4 root 3. Find its side

Answer 1

Answer:

area of equilateral triangle=√3/4a^2

4√3=√3/4a^2

a^2=4x4

a=4

therefore side of the given equilateral triangle is 4

Answer 2

Answer: 4

Step-by-step explanation:

Area of an Equilateral Triangle = $\frac{\sqrt{3} }{4} a^{2}$

where a = length of the side

given  

a = $4\sqrt{3}$

that means

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

this can be re written as

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

taking square root on both sides :

we get a = 4
