Let \"+s+\" = the length of the shortest side in cm
\n" ); document.write( "The lengths of the sides are:
\n" ); document.write( "\"+s+\", \"+3s+\", and \"+3s+\", all in cm
\n" ); document.write( "-------------------------------
\n" ); document.write( "\"+s+%2B+3s+%2B+3s+=+42+\"
\n" ); document.write( "\"+7s+=+42+\"
\n" ); document.write( "\"+s+=+6+\"
\n" ); document.write( "and
\n" ); document.write( "\"+3s+=+18+\"
\n" ); document.write( "The sides are 6, 18, 18, all cm
\n" ); document.write( "-----------------------------
\n" ); document.write( "check:
\n" ); document.write( "\"+6+%2B+18+%2B+18+=+42+\"
\n" ); document.write( "\"+42+=+42+\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
