Note: All id's must be unique and if not please do
To change the textarea to 30 rows (assumed :one textarea) you can do like
$('textarea').attr("rows","30")
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

You can add type of control in the selector with id to get specific element you want. You can use attribute selector with type of element as under. In the attribute selector use the *
as a wild card for elements containing the given string in the id.
$("textarea[id*=rule_definition]").attr('rows','30');
If you are sure the id will start with rule_definition
you can use starts with selector using ^
instead of *
$("textarea[id^=rule_definition]").attr('rows','30');
