How do you find out the length of alpha -helix and beta -helix?

This is quite simple. Using stoichiometry to keep track of units, simply take the number of amino acids in the particular alpha helix and multiply by 15 angstroms. This is the length the alpha helix is advanced along the length axis by each additional A.A. For a beta helix it become more difficult however and you must know how many sheets you are taking into account.
