Infinitely many.
Select any number, W, such that 0 < W ≤ 15. Since numbers are infinitely dense, there are infinitely many possible values for W. Let L = 30 - W. Then W ≤ L so each choice of W leads to a unique pair (W, L).
Now, a rectangle with width W cm and length L cm has a perimeter of 2*(L+W) = 2*(30 - W + W) = 2*30 = 60 cm, as required.

How many rectangles can be drawn with 18cm as the perimeter?
An arbitrary large number is the answer for anyrectangle, up to that with a length of 9cm, and 0cm as the width will have a perimeter of 18cm.Similarly, any rectangle up to that with sides 0cm long, and a width of 9cm will have your 18cm perimeter.
