Unit 9: Perimeter and Area
Two of the most common applications of Geometry are area and perimeter. Owning a home gives you plenty of opportunities to use these concepts. Thinking of buying a cordless electric lawnmower? The manufacturer will give you an estimate of the mower's battery life using square feet. If your yard is extremely large and your mower's battery life is not long enough, it might take you multiple sessions to get it all mowed. Are you buying new carpeting for your home? It is sold in square feet or square yards. You definitely do not want to buy too much carpeting or too little carpeting. You are not just going to eyeball it and make a guess. You will want to measure everything carefully, and then order a bit more, giving yourself some leeway.
Like area, perimeter is often used in home ownership. If you install fencing around your yard, you are going to calculate the perimeter before you buy the fencing. If you are forced to run wiring around the walls of a room, it is vital that you know how much wiring you will need.
