1. The side of the square is given. Find the perimeter.

The C.E.O of the company has contacted you to develop a C# windows-based application to keep track of these information. Requirements:

1.When the CEO login, he is to see all calls placed by a particular employee, but the

 Receptionist is responsible of only the calls record entry.

2.The application must be a three-tier application with database and business logic

3.The system must keep information of when a particular call was placed, who made the call, call duration, the cost of the call,

the call type(local or foreign, cell phone or fixed line)

4.The call cost must be based on per minute billing. If the time duration is 30 seconds or more,

 it should be counted as one minute. If the total call duration is some minutes and plus less

 than 30 seconds, only the minute(s) should count. The seconds should be ignored.

5.Calls Cost

  - Cell phone = GHC 0.50

  - fixed line = GHC 0.30
