Question 936425
{{{2(L+W)=26}}}
{{{L+W=13}}}
.

.
{{{3W=L/4}}}
{{{W=L/12}}}
Substituting into the perimeter equation.
{{{L+L/12=13}}}
{{{(12/12)L+L/12=13}}}
{{{(13/12)L=13}}}
{{{L=12}}}
{{{12+W=13}}}
{{{W=1}}}
So originally the rectangle was 12x1.
To get the square side, triple the width.
{{{S=3(1)=3}}}
So the perimeter of the square is,
{{{P[s]=4(3)}}}
{{{P[s]=12}}}{{{cm}}}
