let width be x
\n" ); document.write( "length will be 2x
\n" ); document.write( "..
\n" ); document.write( "6 is decreased from both
\n" ); document.write( "x-6
\n" ); document.write( "2x-6
\n" ); document.write( "2x^2-(x-6)(2x-6)= 108
\n" ); document.write( "2x^2-(2x^2-6x-12x+36)=108
\n" ); document.write( "2x^2-2x^2+18x-36=108
\n" ); document.write( "18x=108+36
\n" ); document.write( "18x=144
\n" ); document.write( "x=144/18
\n" ); document.write( "x=8 which is the width
\n" ); document.write( "Length = 2x = 16 units
\n" ); document.write( "
\n" );
