Let $\"+w+\"$ = width of garden in meters
\n" ); document.write( " $\"+3w+%2B+12+\"$ = length in meters
\n" ); document.write( "------------------------------
\n" ); document.write( " $\"+w%2A%28+3w+%2B+12+%29+=+180+\"$
\n" ); document.write( " $\"+3w%5E2+%2B+12w+=+180+\"$
\n" ); document.write( " $\"+w%5E2+%2B+4w+-+60+=+0+\"$
\n" ); document.write( " $\"+%28+w+%2B+10+%29%2A%28+w+-+6+%29+=+0+\"$ ( by inspection )
\n" ); document.write( " $\"+w+=+-10+\"$ ( can't use -width must be positive )
\n" ); document.write( " $\"+w+=+6+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+3w+%2B+12+=+3%2A6+%2B+12+\"$
\n" ); document.write( " $\"+3w+%2B+12+=+30+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "The dimensions are: 6 m by 30 m
\n" ); document.write( "--------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+6%2A30+=+180+\"$ m2
\n" ); document.write( "OK\r
