The \"perimeter\" of a rectangular field is \"P=2%28a%2Bb%29\" where \"a\" is the length of the field, and \"b\" is the width of the field.\r

\n" ); document.write( "\n" ); document.write( "\"P+=+294+\"\r
\n" ); document.write( "\n" ); document.write( "\"a+=+86+\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"294=+2%2886%2Bb%29\"\r
\n" ); document.write( "\n" ); document.write( "\"294%2F2++=+86%2Bb\"\r
\n" ); document.write( "\n" ); document.write( "\"147+=+86%2Bb\"\r
\n" ); document.write( "\n" ); document.write( "\"147+-+86+=+b\"\r
\n" ); document.write( "\n" ); document.write( "\"61yd+=+b\"...........the width of the field\r
