Question 1053895
{{{Area=(2W)*W}}}
{{{Area=2W^2}}}
{{{Perimeter=2(2W)+2W}}}
{{{Perimeter=4W+2W}}}
{{{Perimeter=6W}}}
{{{2W^2=6W}}}
Since {{{W}}} is not zero, the equation simplifies to {{{2W=6}}} ,
meaning {{{L=6}}} ,
and {{{W=6/2}}} or {{{W=3}}} .
So, the tract is 6 miles long and 3 miles wide.
That makes the perimeter 18 miles, and the area 18 square miles.
