For the rectangle,
\n" ); document.write( "\"perimeter=2%2813.5cm%2B6.5cm%29=2%2820cm%29=40cm\" .
\n" ); document.write( "So \"perimeter=40cm\" .
\n" ); document.write( "For the square,
\n" ); document.write( "\"x\"= length of the side of the square, so \"perimeter=4x\" .
\n" ); document.write( "since the square must have the same perimeter.
\n" ); document.write( "\"system%28perimeter=40cm%2Cperimeter=4x%29\"---> \"4x=20cm\"--->\"x=20cm\"--->\"x=5cm\"
\n" ); document.write( "The length of the side of a square is \"highlight%285cm%29\" .
\n" ); document.write( "
\n" );
