Trying to Figure Out Problem

Question

S=2lw+2lh+2wh

solve formula for l in terms of s, w, h

solve formula for h in terms of s, l, w

for some reason I can’t get correct answers if you can please show step by step

Answer 1

S = 2LW + 2LH +2WH solve for L

S - 2WH = 2LW + 2LH

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

(S-2WH)/(2W + 2H) = l

S = 2LW + 2LH +2WH solve for H

S - 2LW = 2LH + 2WH

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

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