@fazalazizmazhari; correctly answered the question. Good effort.
The detailed solution of the question is as follows :
Number of seconds in a minute = 60
Number of minutes in an hour = 60
Number of hours in a day = 24
∴ Number of seconds in a day = 60 × 60 × 24 = 86400
Number of days in a year = 365
∴ Number of seconds in a year = 86400 × 365 = 31536000
Number of seconds in 7 years = 7 × 31536000 = 220752000 = 2.20752 × 108.
