    $\displaystyle S = lw + wh + lh$
    $\displaystyle S=w(l+h)+lh$
    $\displaystyle S-lh=w(l+h)$
    $\displaystyle \frac{S-lh}{l+h}=w$

    S = lw + wh + lh
    $\displaystyle S = lw + wh + lh$
    $\displaystyle S - lw = wh + lh$
    $\displaystyle S - lw - wh = lh$
    $\displaystyle - lw - wh = lh - S$
    $\displaystyle lw + wh = S - lh$ (multiplied by -1 here)
    $\displaystyle w(l + h) = S - lh$
    $\displaystyle w= \frac {S - lh}{l+h}$
