Question 980660
w width, L length, p perimeter

p=74


{{{system(L=w+7,2w+2L=p)}}}


{{{2w+2(w+7)=p}}}
{{{2w+2w+14=p}}}
{{{4w=p-14}}}
{{{w=p/4-14/4}}}
{{{w=p/4-7/2}}}
or maybe easier to use as {{{w=(p-14)/4}}}


{{{L=(p/4-14/4)+7}}}
{{{L=p/4-14/4+28/4}}}
{{{L=(p+14)/4}}}


--
{{{w=(74-14)/4=15}}}, width
