Question 877037
How length L and width w are related as described:
{{{L=2w}}}


Using L and w in perimeter 48:
{{{2w+2L=48}}}
That can be simplified...
{{{w+L=24}}}
And L can be substituted as found from description:
{{{w+2w=24}}}
{{{3w=24}}}
{{{w=24/3}}}
{{{highlight(w=8)}}} and {{{highlight(L=16)}}}.
