Answer:
Time period = no. Of oscillations /time
T = 20/5 = 4 sec
Freq = 1/time period
Freq = 1/4 =0.25Hz

Explanation:
the number of oscillations per second of the vibrating body is known as frequency of oscillation
Frequency = total number of oscillation
total time taken
= 20/5
=10 Hz
Time period is the time taken to complete one oscillation. It is also inverse of frequency .
= Time period = 1/10
= 0.15
therefore frequency = 10 Hz
time period = 0.1 second
