Let $\"d\"$ = diagonal
\n" ); document.write( " $\"d%5E2+=+12%5E2+%2B+4%5E2+%2B+3%5E2\"$ (in in2)
\n" ); document.write( " $\"d%5E2+=+144+%2B+16+%2B+9\"$
\n" ); document.write( " $\"d%5E2+=+169\"$
\n" ); document.write( " $\"d+=+sqrt%28169%29\"$
\n" ); document.write( " $\"d+=+13\"$ in \n" ); document.write( "
