Write and test a program for project 6 on p. 93

Develop the case study similar to p. 67-68 of textbook before you attempt 
to write the program.

The yard and house dimensions (length and width of each) and the mowing 
rate (2 square feet a second) should be data items. Use meaningful 
variable names (eg, house_wid for house width).

Bring your case study and a program ready to type in to lab. Your 
instructor will check off your case study in lab.
