Question 1009007
w and L, dimensions of the rectangle;
x, side length of a square;
Translating the description----------{{{system(wL=6*x^2,L=22,w=x)}}}


The question means, to solve for x.


{{{wL=6x^2}}}
{{{w*22=6x^2}}}
{{{x*22=6x^2}}}
{{{6x^2-22x=0}}}
{{{3x^2-11x=0}}}
{{{x(3x-11)=0}}}


{{{3x-11=0}}}
{{{3x=11}}}
{{{highlight(x=11/3)}}}


The other solution, x=0, is meaningless.
