There is no possible way to. You can only add up all the sides to get the perimeter.

It is not impossible. You can get the perimeter from area very easily.
First, you find the square root of the area, which will be the length of each side (assuming it is a square).
Then, once you've found the length of each side, you multiply it by 4, and you should have the perimeter. (:

Not exactly. If I know the side lengths, I can still find the perimeter
You square-root the area
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
To find the perimeter you add and to find the area we multiply.
If you know the area the divide area by length if you know perimeter subtract it by 2xlength and divide by 2
