Subject: erb question --urgent help needed?

i don't know how to explain my problem
here i am showing it by an example

<%
string="Hello Ruby ,How are you"  # any String object
width=28                          # because width of the below erb tag
is 28
%>
<%=p "%#{-width}s"%string %>

the answer is

=>"Hello Ruby ,How are you                 "



in above erb tag ("<%=p "%#{-width}s"%string%>") length is 28
so i assigned width=28

here is my question
how to define the width at dynamically for any type of erb tags ?
