    ok

    S = 2LW + 2LH + 2WH

    S = W(2L+2H) + 2LH

    S - 2LH = W(2L+2H)

    (S-2LH)/(2L+2H) = W

    All you need to do is isolate W.

    S=2lw+2lh+2wh

    2lw=S-2lh+2wh

    w=(S-2lh+2wh)/2l

    S - 2LH = W(2L + 2H)

    S - 2LH/(2L + 2H) = W

    S=2LW+2LH+2WH

    S-2LH= 2LW+2WH

    S-2LH/2L=W+2WH

    S-2LH/2L/2H=2W

    S-2LH/2L/2H/W=W

    S-H/2H/W=W

    S/H/W=W

    S= 2LW+ 2LH+ 2WH

    S -2LH =2W(L+H)

    W = (S-2LH)/(2)(L+H) ..............ANS
