One simple way to do what you're doing is to change the value of Perl's input record separator from an end-of-line to a ^D:

my $FileLocation = '/home/RND/Sample.txt';
open my $FILE, '<', $FileLocation or die "$!";
my @LineDetails = do { local $/ = chr(4); <$FILE> };
map { print "$_\n" } @LineDetails;

This eliminates both for loops.

Note that the foreach keyword is actually a synonym for the for keyword, so in your original post, you can have replaced "foreach" with "for" in both places, which also simplifies your code.
