We have perimeter P = 2L + 2W = 310 and
\n" ); document.write( "L = 2W + 10
\n" ); document.write( "Substitute this into the first equation and get
\n" ); document.write( "2(2W + 10) + 2W = 310
\n" ); document.write( "4W + 20 + 2W = 310
\n" ); document.write( "6W = 290
\n" ); document.write( "W = 48 1/3 m
\n" ); document.write( "L = 2(48 1/3) + 10 = 106 2/3 m
\n" ); document.write( "
\n" );
