Group Activity – Geometry The Buyer family recently purchased a foreclosed home at a real estate auction. The Buyers got a great deal on the price of the home, but the home needs many repairs. The Buyers decide to install new fl oor molding (baseboards) in the living room. The rectangular living room is 24 ft long and 15 ft wide. The fl oor plan of the room is shown below. 24 ft 15 ft Entryway 1) Mr. and Mrs. Buyer are going to a home improvement store to purchase the fl oor molding for the living room. They each estimated the amount of fl oor molding that is needed (ignoring the entryway for now). Mr. Buyer thinks that they will need 360 ft of molding, and Mrs. Buyer thinks they will need 78 ft of molding. Which estimate is correct? Give reasons to support your answer. 2) Describe in your own words how to determine the perimeter of a rectangle if you know the length and width. 3) Calculate the amount of fl oor molding required for all six of the rooms in the table below. Room Length Width Calculations: 2l 2w P Perimeter Living 24 ft 15 ft 2(24) 2(15) 48 30 78 78 ft Dining 16 ft 12 ft Family 30 ft 16 ft Bedroom 1 18 ft 15 ft Bedroom 2 14 ft 14 ft Bedroom 3 13 ft 13 ft 4) In the rooms above, there is a total of 4 entryways and 3 doorways. Each entryway is 7 ft wide and each doorway is 3 ft wide. Accounting for the space in the entryways and doorways, how much molding is needed for all six rooms? 5) The type of fl oor molding that the Buyers chose is sold in lengths of 12 ft for $3 each. How many lengths will they have to buy? What will the total cost be? 340 CHAPTER 4 Basic Geometry Concepts and Algebra www.mhhe.com/messersmith
