Let width be x
\n" ); document.write( "Let length be y\r
\n" ); document.write( "\n" ); document.write( "y = 2x + 10\r
\n" ); document.write( "\n" ); document.write( "2x + 2y = P
\n" ); document.write( "2x + 2(2x + 10) = 140
\n" ); document.write( "2x + 4x + 20 = 140
\n" ); document.write( "6x + 20 = 140
\n" ); document.write( "6x = 120
\n" ); document.write( "x = 20\r
\n" ); document.write( "\n" ); document.write( "y = 2x + 10 = 2(20) +10 = 50\r
\n" ); document.write( "\n" ); document.write( "Final Answer:
\n" ); document.write( "Width = 20 meters
\n" ); document.write( "Length = 50 meters
\n" ); document.write( "
\n" );
