The formula for perimeter is
\n" ); document.write( "(i) P = 2L + 2w
\n" ); document.write( "we also know that
\n" ); document.write( "(ii) w = (1/2)L + 2
\n" ); document.write( "by substitution, we get
\n" ); document.write( "(iii) $\"40+=+2L+%2B+2%28%281%2F2%29L+%2B+2%29\"$
\n" ); document.write( "(iv) $\"40+=+2L+%2B+L+%2B+4\"$
\n" ); document.write( "(v) $\"36+=+3L\"$
\n" ); document.write( "L = 12
\n" ); document.write( "This means w = 8.
\n" ); document.write( " \n" ); document.write( "

\n" );
