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
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]
