Step-by-step explanation:
In business, a fixed period refers to the duration of a lease agreement. A regular rent is the amount paid on a recurring basis for using a property. When both the landlord and tenant agree to terminate the lease, they can do so by providing a 30-day written notice. This means that after the notice period, the lease agreement will come to an end.
