If it is a 17 yard by 9 yard room then 153 square yards!
23.67 square yards
There are: (18/3) times (17/3) = 34 square yards

32.11 square yards. * * * * * * * -- 321/9 square yards on the floor -- another 321/9 square yards on the ceiling -- more square yards on the walls, but in order to count them, you have to know the height of the ceiling above the floor.
1.9 square yards.
There are: 12/3 times 17/3 = 22.67 square yards rounded to two decimal places
First, you have to find the dimensions of the room in square feet. Multiplying length times width, 15*17 = 255. Then, knowing that 1 square yard equals 9 square feet, you take 255/9 and find the room contains 85/3 square yards or 24 and 1/3 square yards.
17' x 13' (221 square feet) = 24.55 square yards.
12' x 17' (204 square feet) = 22.66 square yards.
17 and 1/3 square yards.
You must first assume that the room is 17 ft x 16 ft and not some other units - for example 17 yards by 16 yards. In that case the room is 17*16 = 272 square feet and, irrespective of the width of the carpeting, you will need 272 square feet of carpet.
