I ran your code and I get this output

 soy mejicano con el pelo negro y los ojos marrones

If you want to store the output in a file then you can do something like this -

  
open (FH, '>', "junk") or die $!; 
 $en_text = $obj->translate( 'source' => 'English',
                            'destination' => 'Spanish',
                            'text' => "i am mexican with black hair an
+d brown eyes",
                            'delimiter' => "\n\n",
                            'ofh' => \*FH);
[download]

This will write the translation into a file.

If you do not want that then just remove the 'ofh' from the call. When i do that it returns the text and it is stored in $en_text. You can just print it or you can then push this text into an @array of your choice.

Something like this ? -

#!/usr/bin/perl

 use strict;
 use warnings;

 use WWW::Babelfish;
 use Data::Dumper;

# open (FH, '>', "junk") or die $!;

 my $obj = new WWW::Babelfish( service => 'Google', agent => 'Mozilla/
+8.0');
 die( "Babelfish server unavailable\n" ) unless defined($obj);

 my @sentences = ("I would like to translate this sentence into Spanis
+h", "Because i am mexican with black hair and brown eyes");
 my @translations = ();

 for (@sentences) {
    my $en_text = $obj->translate( 'source' => 'English',
                                'destination' => 'Spanish',
                                'text' => $_,
                                'delimiter' => "\n\n");

    die("Could not translate: " . $obj->error) unless defined($en_text
+);
    push(@translations,$en_text);
}

print Dumper (@translations);

Output

$VAR1 = "Quisiera traducir esta oraci\x{f3}n a espa\x{f1}ol";
$VAR2 = 'Porque soy mejicano con el pelo negro y los ojos marrones';
