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