You can put this solution on YOUR website!
let side of square be x
\n" ); document.write( "Area = x^2
\n" ); document.write( "it is decreased by 2
\n" ); document.write( "so new length = x-2
\n" ); document.write( "area = (x-2)^2
\n" ); document.write( "..
\n" ); document.write( "The area decreases by 36 m^2
\n" ); document.write( "x^2-(x-2)^2=36
\n" ); document.write( "x^2-x^2+2x-4=36
\n" ); document.write( "2x-4 = 36
\n" ); document.write( "2x=40
\n" ); document.write( "x= 20 m
\n" ); document.write( "...
\n" ); document.write( "side = 20m
\n" ); document.write( "...
