Question 195644
{{{P=4s}}} Start with the perimeter of a square formula



{{{8x+24=4s}}} Plug in {{{P=8x+24}}}



{{{4(2x+6)=4s}}} Factor out 4 from the left side



{{{2x+6=s}}} Divide both sides by 4.



{{{s=2x+6}}} Rearrange the terms.



{{{A=s^2}}} Move onto the formula for the area of a square.



{{{A=(2x+6)^2}}} Plug in {{{s=2x+6}}}



{{{A=4x^2+24x+36}}} FOIL



So the area is {{{4x^2+24x+36}}}
