All the assignments for this unit are concerned
with the Lawnsword Garden Design Company.
Lawnsword Garden Design Company has a problem,
this is explained below:-

Scenario:
Lawnsword Garden Design specialises in designing
and producing lawns and old-fashioned hay meadows for
clients.
Hay meadows, which contain mixtures of grass and wild
flowers, are always produced by sowing seed.
Lawns may be made by laying prepared turf or by sowing
seed. It is the seed sowing which causes a problem,
since different types of seeds cover different areas.
Ms Jane Lawnsword, who is the proprietor of the business,
spends many hours calculating the amount of seeds required
for each job and she now feels that she should be able
to enlist the help of a computer to ease her workload.
You have volunteered to attempt to solve the “seed sowing
problem” and Ms Lawnsword has passed you details of
one of the pending jobs.

You have volunteered to attempt to solve the “seed sowing
problem” and Ms Lawnsword has passed you details of one
of the pending jobs.
The job details which follow are for the sowing of two lawns
and two fields. The four shapes shown are the four most popular
shapes that the business deals with, so any program should be
able to accept different dimensions for each basic shape.
The job
details are for:
- A rectangular lawn
- A circular lawn
- An L – shaped field
- A field that is rectangular, but includes a circular
pond
In the future Ms Lawnsword wants to use the program to work
out the seeds needed for different combinations of these four
basic shapes so your program should be written with this in
mind. Think of how your program could handle combinations, or
numbers of shapes such as:
- 2 round lawns and 2 ‘L’ shaped fields
- 2 round fields and 3 ‘L’ shaped lawns.
The different shapes are shown below:-
| Lawn1
|
Field 1
|
 |
| Lawn
2 |
Field 2
|
 |
The program
must calculate how much of each seed type should be sown, and
how many whole bags of each seed must be purchased.
The first thing you
need to do is investigate the problem. This means gathering
the necessary information so you can understand the problem
clearly. You need to think about Ms Lawnsword's problem
and specify how you think it could be solved by using a computer
program. You need to specify all of the things that the program
must do, and produce draft versions of the screen layouts.
The documentation you
need to produce for assignment 1 is listed below.

Documentation required
- Describe the problem
- Describe what a program would have to do to
solve this problem
- State what the program will need to output and
in what units
- Draw draft input forms and output forms
- Enter the dimensions required into the drawings
and use these to help you decide on the calculations
which will be used (hand in the drawings with
your other work)
- Make notes of the calculations to be used
- List the data to be input, output and stored
- List the main stages in processing of data from
