In Perl, a 2-D array is an array of references to 1-D arrays.
Look at Data Type: Array in the Tutorials section of Perl Monks.
A Perl 2-D array can have a different number of "columns" on each "row". 
#!/usr/bin/perl
use strict;
use warnings;

my @ar1 = (["one", "two"], ["three", "four", "five"]);
my $count = scalar @{ $ar1[1] };
print "count: Elements in 2nd Row = $count\n"; 

print "number of dimensions =", scalar @ar1, "\n";

my $total_elements;
foreach my $row_ref (@ar1)
{
    $total_elements += @$row_ref;
}

print "total elements in array:ar1=$total_elements\n";

__END__
count: Elements in 2nd Row = 3
number of dimensions =2
total elements in array:ar1=5
