\n" ); document.write( "L=length; W=width; P=perimeter=14cm
\n" ); document.write( ".
\n" ); document.write( "2W=(1/3)L . Multiply each side by 3.
\n" ); document.write( "6W=L . Use this to substitute for L.
\n" ); document.write( ".
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "14cm=2(L+W)
\n" ); document.write( "7cm=L+W . Substitute for L from above.
\n" ); document.write( "7cm=6W+W
\n" ); document.write( "7cm=7W
\n" ); document.write( "1cm=W
\n" ); document.write( "ANSWER 1: The width is 1 cm.
\n" ); document.write( ".
\n" ); document.write( "L=6W=6(1cm)=6cm
\n" ); document.write( "ANSWER 2: The length is 6 cm.
\n" ); document.write( ".
\n" ); document.write( "CHECK:
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "14cm=2(6cm+1cm)
\n" ); document.write( "14cm=2(7cm)
\n" ); document.write( "14cm=14cm\r
