Question 990475
List all facts.
Total Fencing, 143 meters;
L, length, w width;
L=4w;
Segment sizes forming the rectangular region are  L+L+L+w+w, because one of the L is used as a physical divider.


Form Equation.
{{{3L+2w=143}}}


Substitute for L.
{{{3(4w)+2w=143}}}
{{{14w=143}}}
{{{w=143/14}}}
{{{w=10&3/14}}}
Possibly strange result because, "divided along its length into two equal parts."


The LENGTH is not really being divided; the division is ALONG the LENGTH, meaning the width is what is being divided.
Really want:
{{{highlight_green(2L+3w=143)}}}
{{{2(4w)+3w=143}}}
{{{11w=143}}}
{{{w=143/11}}}
{{{highlight(w=13)}}}
and
{{{highlight(L=54)}}}
