Question

The length, 1 cm, of a simple pendulum is directly proportional to the square of its
period (time taken to complete one oscillation), T seconds. A pendulum with a length
of 220.5 cm has a period of 3 s.
(i) Find an equation connecting I and T.
(ii) Find the length of a pendulum which has a period of 5 s.
(iii) What is the period of a pendulum which has a length of 0.98 m?
hurry up please ​
