Perimeter P = 2L + 2W = 84. We also have
\n" ); document.write( "L = 4W + 8
\n" ); document.write( "Now substitute that into the first equation and get
\n" ); document.write( "2(4W + 8) + 2W = 84
\n" ); document.write( "8W + 16 + 2W = 84
\n" ); document.write( "10W + 16 = 84
\n" ); document.write( "10W = 68
\n" ); document.write( "W = 6.8 m
\n" ); document.write( "L = 4(6.8) + 8 = 35.2 m
\n" ); document.write( "
\n" );
