It is impossible

Not exactly. If I know the side lengths, I can still find the perimeter

no

You square-root the area

Divide the perimeter by 4 and then square the result to find the area of the square.

no

You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.

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

You can't only using the perimeter. You have to know length and width.

Perimeter equals to 2 times the length plus 2 times the breadth. Area equals to length multiply by breadth
