we have 2 formulas
\n" ); document.write( "(i) $\"L+=+2w-9\"$
\n" ); document.write( "(ii) $\"342+=+2W+%2B+2L\"$
\n" ); document.write( "by substitution, we get
\n" ); document.write( "(iii) $\"342+=+2W+%2B+2%282W-9%29\"$
\n" ); document.write( "and then
\n" ); document.write( "(iv) $\"342+=+6W+-+18\"$
\n" ); document.write( "add 18 to get
\n" ); document.write( " (v) $\"360+=+6W\"$
\n" ); document.write( "divide by 6 to get
\n" ); document.write( "W = 60 meters
\n" ); document.write( "and then
\n" ); document.write( "L = 111 meters \n" ); document.write( "
