Write client and server programs in which a server program accepts the length and breadth of a rectangle from the client program, computes area, sends the computed area to the client program, and displays it by client program.

Output of the Program :
Client side
run:
Client started.
Input: Lenghth and Breadth 4
7
Echoed from server: 28.0
Input: Lenghth and Breadth
Server Side
run:
Server started.
Listening to client…
Length Received from client: 4
Breadth Received from client: 7
