L=2W-5
\n" ); document.write( "PERIMETER=2L+2W
\n" ); document.write( "230=2(2W-5)+2W
\n" ); document.write( "230=4W-10+2W
\n" ); document.write( "6W=230+10
\n" ); document.write( "6W=240
\n" ); document.write( "W=240/6
\n" ); document.write( "W=40 ANSWER FOR THE WIDTH.
\n" ); document.write( "L=2*40-5
\n" ); document.write( "L=80-5
\n" ); document.write( "L=75 ANSWER FOR THE LENGTH.
\n" ); document.write( "230=2*40+2*75
\n" ); document.write( "230=80+150
