You May use the 'List::Util' module for this task.

use strict;
use warnings;
use List::Util('sum');

## Store the hash value
my %hash = (
    'A' => 46,
    'D' => 18,
    'C' => 17,
    'B' => 31
);

## values %hash -> gives the values of the hash
## keys %hash   -> get number of element in this hash 

my $sum = sum (values %hash)/keys %hash;

print $sum;
