Habitat for Humanity Scenario
Congratulations on becoming a Youth Leader for Habitat for Humanity! It is time to start planning
the home you will build for a family in need of shelter.
1) Use Geometer's Sketch Pad to design a home that is one floor and is a total of 130m 2 .
Keep in mind that in this family there are two parents and one child. You will need a minimum of
two bedrooms, a bathroom, a kitchen, and a living room. Include a scale drawing with names of
rooms and dimensions of each. Discuss the reasoning behind your design.
Activity One: Introduction to Geometer's Sketchpad
2) Carpet has been donated for the bedrooms. How much carpeting is needed in m2?
Review: Perimeter and Area of Composite Plane Figures
3) All of the area that is not carpeted will need to be covered with tiles. If a tile is 25 cm by 25 cm,
how many tiles will they need?
Review: Perimeter and Area of Composite Plane Figures
4) The family would like to make the tiles. If the tiles are 7mm thick, how much material will they
need?
Review: Volume of Prisms
5) A well needs to be installed. It will be cylindrical in shape with a depth of 10 metres and a diameter
of 1.3 metres. How many cubic metres of soil will need to be removed for the well?
Review: Volume of Cylinders
6) The family would like a back deck with a railing. 20 metres of railing have been donated. Three
sides of the deck will need railing (the fourth side will be against the house). 2 metres for a walkway
will be without railing.
a) What is the maximum area of a deck that you can build?
b) Add this to your original sketch of the home.
Review: Greatest Area with a Fixed Perimeter
7) The family has had enough top soil donated to create 16 square metres of garden in their back yard to
grow vegetables. They will need to put a put a low fence around the garden to keep out animals.
a) What is the minimum possible perimeter of the garden?
b) Add this to your original sketch of the home.
Review: Smallest Perimeter that surrounds a Fixed Area
