He asked for the number of elements in the HoA. I took that to mean 5 for the following structure:
my %h = (
k1 => [ qw( a b c ) ],
k2 => [ qw( d e ) ],
);
Your solution simply returns the number of elements in a hash. It could be that's what he meant, but that's now how I interpreted his question.
This is wrong.
Not so hasty on the wrong. Fletch and Jenda also interpreted the question like I did.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
