Question 796110
Yes.
{{{x}}}= length of the side of the square.
Folding the square in half, you get a rectangle with length {{{x}}} and width {{{x/2}}}
Its perimeter would be
{{{2*x+2*(x/2)=39}}}
{{{2x+x=39}}}
{{{3x=39}}}
{{{x=39/3}}}
{{{x=13}}}
The area of a square with side length {{{13}}} is
{{{13*13=13^2=169}}}
