You can put this solution on YOUR website!
Perimeter P = 2L + 2W = 48 and W = (1/3)L (or L = 3W)
\n" ); document.write( "Now substitute that into your formula and get
\n" ); document.write( "2(3W) + 2W = 48
\n" ); document.write( "6W + 2W = 48
\n" ); document.write( "8W = 48
\n" ); document.write( "W = 6 cm
\n" ); document.write( "L = 3W = 18 cm
\n" ); document.write( "
\n" );
