Question 207677
# 1


{{{A=2h(L+w)}}} Start with the given equation.



{{{A/(2(L+W))=h}}} Divide both sides by 2(L+W).



{{{h=A/(2(L+W))}}} Rearrange the equation



So the solution is {{{h=A/(2(L+W))}}}

# 2


{{{A=2h(L+w)}}} Start with the given equation.



{{{A=2hL+2hw}}} Distribute



{{{A-2hW=2hL}}} Subtract 2hW from both sides.



{{{(A-2hW)/(2h)=L}}} Divide both sides by 2h.



{{{L=(A-2hW)/(2h)}}} Rearrange the equation



So the solution is {{{L=(A-2hW)/(2h)}}}
