The perimeter of square is 4 x length If you have perimeter only divide by 4 to get length and The area of square is length x length If you already have length that is all you need to know

The length of the side of a square with the given area of 81m squared is: 9 meters.

Square root the area. The length and width of a square are always the same and length times width is the area so this is how you get the area.

The length of the side of a square of area x square units is sqrt(x) units.

Yes, if it is a square the Area=A=l2 where l is the length and If you are given the area, then l=square root (A)

If the area is already given, there should also be either width or length given. Do the area, divided by the length or the width. For example, the area divided by the width equal the length. Hope it helps.

The length of a side is the square root of the area.

It is the same as its length, and if that is not given, it is the square root of the area.

Given the length of the diagonal of the square ... call it 'D units'. The area of the square is (1/2 D2) (same units)2.

i think you find the square root of the area. that's the length and the width, so you multiply it.

If the side length is s units then the area is s2 square units. So, given the area, take the principal square root.

0.0625 square units

If you are given the area of the square, then the length of each side is the square root of the area. If you are given the length of the diagonal of a square, then the lenght of each side is equal to the length of the diagonal divided by the square root of 2. l=sqrt(a) l=d/[sqrt(2)] l=length of side, d=diagonal, a=area, sqrt means square root

The length of each side of a square is numerically equal to the square root of the area.

length = 484/width

All four sides of a square are of equal length. To find the area, you square the length of one side. To find the length of one side from the given area, find the square root of the area. In this case, the square root of 25 is 5. Hence, the length of a side is 5 yards.

For a given perimeter, its a square.

Just multiply the length times the width.

The perimeter of a square is four times the length of one side. Since the length of the side is not given here, you have to figure that out first. Note that the area of a square is the square (the second power) of the length of one side.

This is equal to a square with lengths of 63.61 metres. You however cannot associate length with area unless been given another length (unless it's a square where area is length squared)

The length and width can't be determined since it is a rectangle. A length would need to be given, or it would have to be a square.

The area of a square is the square of its side length.

You find the square root an then label it as the side.

An acre is a measure of area. It is already a measure of length squared, and an acre is equal to 4,840 square yards.The term "square" is incorrectly applied to the term "acre" as the latter is already length squared.

The area of a square is given by multiplying length by width. Since these are equal, it is the length-squared. Thus, if the area is 256^2 square feet, then the length must be 256 ft. On the other hand, if your question is: Area = 256 sq ft., what is the length? Then the answer is 16 ft. This, by the way, is the relevance of the square root in geometry.
