One side $\"+s+\"$ , of the square field is
\n" ); document.write( " $\"+s%5E2+=+60025+\"$
\n" ); document.write( " $\"+s+=+sqrt%28+60025+%29+\"$
\n" ); document.write( " $\"+s+=+245+\"$
\n" ); document.write( "Perimeter = $\"+4s+\"$
\n" ); document.write( " $\"+4s+=+4%2A245+\"$
\n" ); document.write( " $\"+4%2A245+=+980+\"$
\n" ); document.write( " $\"+980%2F18000++=+.05444+\"$
\n" ); document.write( " $\"+.05444%2A60+=+3.267+\"$
\n" ); document.write( " $\"+.267%2A60+=+16+\"$
\n" ); document.write( "He returns to starting point in 3 min 16 sec \n" ); document.write( "

\n" );
