Call the length and width, L and W. Then we have
\n" ); document.write( "L = 2W and
\n" ); document.write( "Perimeter P = 2L + 2W = 30
\n" ); document.write( "Now substitute and get
\n" ); document.write( "2(2W) + 2W = 30
\n" ); document.write( "4W + 2W = 30
\n" ); document.write( "6W = 30
\n" ); document.write( "W = 5 and then
\n" ); document.write( "L = 10
\n" ); document.write( "
\n" ); document.write( "
\n" );
