You can put this solution on YOUR website!
let length be 2x
\n" ); document.write( "width will be x
\n" ); document.write( "Perimeter = 2*(L+W)=54
\n" ); document.write( "2*(2x+x)=54
\n" ); document.write( "2*3x=54
\n" ); document.write( "6x=54
\n" ); document.write( "x=9 width
\n" ); document.write( "length = 18
\n" ); document.write( "
\n" );
