Perl int function solved

Hello, I have the below perl function int to return the integer value from the expression but it is not. I am not sure if something misses out here. Any help on this? Thanks in advance.

# Code sample Start
my $size = int (`1134  sample_text_here`);
print "$size \n";
# Code end

I got it, it was the issue with quotes. A double quote worked fine for me. Thanks
