/*
1. Write a program that asks the user to enter the width and length of a room.

2. Once these values have been read, your program should compute and display the area of the room.

3. The length and the width will be entered as **floating-point numbers**.

4. Include units in your prompt and output message; either feet or meters, depending on which
unit you are more comfortable working with.
