Respuesta :

If you want to solve for L instead of A, you must divide the area by the width instead.

It would look like this:  A = LW
                                    LW = A
                                    LW/W = A/W
                                    L = A/W

[tex]a \: = lw \: \\ by \: transposition \: \\ lw \: = a \\ l \: = \frac{a}{w} [/tex]
