Question 270962
the area of a square is
{{{x^2=A}}}
the perimeter of a square is
{{{4x=P}}}
_
if A=225 then
{{{x^2=225}}}
{{{sqrt(x^2)=sqrt(225)}}}
{{{x=15}}}
_
if x=15 then
{{{4(15)=P}}}
{{{highlight(60=P)}}}
__________________________
the area of a rectangle is
{{{LW=A}}}
the perimeter of a rectangle is
{{{2L+2W=P}}}
_
If A=130 and W=10 then
{{{L10=130}}}
{{{L=13}}}
_
If L=13 and W=10 then
{{{2(13)+2(10)=P}}}
{{{(26)+(20)=P}}}
{{{highlight(46=P)}}}
