Your search is going to take a very long time because you haven't got enough information to proceed.

Insufficient data for a unique answer.

4. Suppose we are given the area of a triangle. Let A.
We have to find the tree sides a,b,c.

No need to be the unique answer.

s=(a+b+c)/2
A=s(s-a)(s-b)(s-c)

How to find a,b,c?

A=s(s-a)(s-b)(s-c)

How to find a,b,c?
Heron's formula:

A = $\sqrt{s(s-a)(s-b)(s-c)}$

for an equilateral triangle
in which a=b=c

c = $\sqrt { \dfrac{4A}{\sqrt 3 } }$
