Given the below formula for perimeter of a rectangle;

To make l(length) the subject of formula, we first of all need to subtract 2w from both sides of the equation;

The next step is to divide both sides of the equation by 2;

$\begin{gathered} l=(P-2w)/(2) \\ \therefore l=(P)/(2)-w \end{gathered}$

So, the formula for finding length is (l = P/2 - w).
