Best Answer

You have only one equation [ A = ( L ) ( W ) ] and two unknowns [ L and W ]. You need one more equation to find L and W. The other equation might be the Perimeter equation [ P = 2L + 2W ] or

ratio of length to width [ L/W or W/L ].

You'll need to know either its length or width and then divide it into its area to find one or the other.

Knowing the area only is not enough. Otherwise, you can get infinite of rectangles with different length sides.
