Question 894369
First, write the equation for the perimeter of a rectangle,
{{{P=2(L+W)=174}}}
{{{L+W=87}}}
.
.
.
Now write the relationship between length and width,
{{{L=2W-3}}}
Substitute this value into the perimeter equation and solve for {{{W}}}.
{{{(2W-3)+W=87}}}
{{{3W=90}}}
{{{W=30}}}feet
Now,
{{{L=2(30)-3}}}
{{{L=60-3}}}
{{{L=57}}}feet
