Question 317723
Start with square of side s.
Go to a rectangle with sides, (s+3) and (s-2)
{{{A=(s+3)(s-2)=24}}}
{{{s^2-2s+3s-6=24}}}
{{{s^2+s-30=0}}}
{{{(s+6)(s-5)=0}}}
Two solutions:
{{{s+6=0}}}
{{{s=-6}}}
This solution doesn't make sense in this problem.

{{{s-5=0}}}
{{{s=5}}}
{{{P=s+3+s+3+s-2+s-2=4s+2=4(5)+2}}}
