If the lengths of the sides of a rectangle
\n" ); document.write( "are \"x\" and \"y\",
\n" ); document.write( "\"perimeter=2x%2B2y\"
\n" ); document.write( "In the rectangle of the problem, \"highlight%28y=11cm%29\" and \"perimeter=42cm\"
\n" ); document.write( "\"42cm=2x%2B2%2A11cm\"-->\"42cm=2x%2B22cm\"-->\"42cm-22cm=2x\"-->\"20cm=2x\"-->\"x=20cm%2F2\"-->\"highlight%28x=10cm%29\"
\n" ); document.write( "The dimensions of the rectangle are 11cm by 10cm.
\n" ); document.write( "
\n" );
