The area of an Equilateral triangle is given by the formula A= 3pi squared/4(s)Squared. Which formula represents the length of equilateral triangle’s side S?

The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is .

Step-by-step explanation:

We are given the area of an Equilateral triangle which is A = . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

So, the area of an equilateral triangle =  

where, s = side of an equilateral triangle

A  =  

Cross multiplying the fractions we get;

Now. moving to the right side of the equation;

Taking square root both sides we get;

Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

the surface area is 124cm²
