Question

(a) William measures the dining room ceiling to see how much molding he will need to go around the perimeter of the rooms ceiling. William measured the length of the dining room to be 8 3/4 ft. and the width to be 10 7/8 ft. How much molding does William need for the dining room ceiling? Show your work.
My answer: 2(8.75) + 2(10.875) = 39.25 or 39 1/4 ft.
(b) Williams wife measures the window and adds the measurement to the dining room ceiling measurement. She tells her husband that they need a total of 65 1/8 ft of molding to remold the ceiling and the window. How much molding is needed for the window? Show your work.
(c) William begins to plan his work on the window and finds that the pieces for the height of the window will measure 6 3/4 ft each. How long will he cut each piece of molding for the width of the window? Explain your answer.
(d) Williams wife says the molding for the window will take almost 50% of the total molding they need. William says it is closer to 1/3 of the molding. Approximately what percent of the total molding will be used for the window and who is closer to the correct answer? Explain your answer.
