Use Pythagoras' theorem
If the only known fact is the length of the diagonal then the width and length of the rectangle CANNOT be determined. The diagonal could be that of a square, or of a rectangle that is very long but quite narrow. Consequently at least one more fact is required such as; the dimension of either the length or the width, or the angle that the diagonal makes to the base of the rectangle or even the area of the rectangle.
That would depend on the length of the rectangle which has not been given but the area of a rectangle is length times width
Divide the area by the width and it will give you the length.

You cannot.

For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
the area of a rectangle = length x widthwe can rearrange this to give uslength of a rectangle = area/ width
Divide area by length and that gives you width.
Divide the area by the width and it will give you the length.

If a rectangle has its length equal to its width, then all four sides are of equal length and it is a square.
You can't. If I tell you the width, the length can still be anything at all.
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.
Given what? Probably measure it
