L=2W-5
\n" ); document.write( "2L*2W=230
\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 FT IS THE WIDTH
\n" ); document.write( "L=2*40-5
\n" ); document.write( "L=80-5
\n" ); document.write( "W=75 FT IS THE LENGTH
\n" ); document.write( "PROOF
\n" ); document.write( "2*40=2*75=230
\n" ); document.write( "80+150=230
\n" ); document.write( "230=230
\n" ); document.write( "
\n" );
