$rtioverview = substr ( $string , 0 , 100 );
Reults = "This is an awe-inspiring tour to the towering headland known

any one can help to solve this problem please?
It depends what you mean by a 'word'. The 'split' operator will split a
string on whitespace, but on that basis there are only twenty words in
your sample string. Take a look at the program below. If it doesn't help
you then please could you give an example showing what result you would
expect from this data?
Cheers,

my @words = split ' ', $string;
print scalar @words, " words:\n";
for my $i (0 .. $#words) {
printf "%3d: %s\n", $i, $words[$i];
}
