Look how many questions there are on this site from people who can't.
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.
If you know the area the divide area by length if you know perimeter subtract it by 2xlength and divide by 2
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.

Divide the perimeter by 4 and then square the result to find the area of the square.
no
You square-root the area
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 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
Only if you also know the shape and proportions. An equilateral triangle, for example.
