let width be x
\n" ); document.write( "width will be 2x
\n" ); document.write( "..
\n" ); document.write( "perimeter = 2L +2W
\n" ); document.write( "2*2x+2*x=120
\n" ); document.write( "6x+2x=120
\n" ); document.write( "/6
\n" ); document.write( "x= 20 feet the width
\n" ); document.write( "length = 2*20 = 40 feet
\n" ); document.write( "...
\n" ); document.write( "CHECK
\n" ); document.write( "20+20+40+40=120
\n" ); document.write( "...
