You could store references to all your hashes in a list, 
@array = ( \%hash1, \%hash2, \%hash3 );

[download]

and then take the size of the array by scalar( @array );
If however, you mean finding the number of keys in a given hash, do this: 

$var = keys %hash2;

[download]
$var now contains the number of key value pairs in the hash.
