Let \"+s+\" = a side of the smaller triangle
\n" ); document.write( "\"+2s+\" = a side of the larger triangle
\n" ); document.write( "----------------
\n" ); document.write( "\"+3s+\" = the sum of the 3 sides of the smaller triangle
\n" ); document.write( "\"+3%2A%28+2s+%29+=+6s+\" = the sum of the 3 sides of the larger triangle
\n" ); document.write( "----------------
\n" ); document.write( "\"+3s+%2B+6s+=+90+\"
\n" ); document.write( "\"+9s+=+90+\"
\n" ); document.write( "\"+s+=+10+\"
\n" ); document.write( "-----------
\n" ); document.write( "\"+3s+\" = the sum of the 3 sides of the smaller triangle
\n" ); document.write( "\"+3s+=+3%2A10+\"
\n" ); document.write( "\"+3s+=+30+\"
\n" ); document.write( "-----------
\n" ); document.write( "\"+3%2A%28+2s+%29+=+6s+\" = the sum of the 3 sides of the larger triangle
\n" ); document.write( "\"+6s+=+6%2A10+\"
\n" ); document.write( "\"+6s+=+60+\"
\n" ); document.write( "-----------
\n" ); document.write( "The rod should be cut into a 30 cm piece
\n" ); document.write( "and a 60 cm piece\r
