255.55 - or in carpet terms, it would be rounded to 255 2/3 yards.
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.
255 square feet. (15 x 17 = 255)
12.5 yards = 37.5 feet 5.5 yards = 16.5 feet
60 feet are 20 yards.
255 feet (1 yard/3 feet) = 85 yards ========
There are 3 feet in one yard. Therefore, 85 feet is equal to 85/3 = 28.3 recurring (that is, 28.333...) yards.
15' x 17' (255 square feet) = 28.3 square yards.
137 yards and 2 feet.
20 yards in 60 feet
3.64 yards is 10.92 feet (yards x 3 = feet).
85 feet is 28.33 yards. (divide feet by three to get yards)
24 yards is 72 feet (yards x 3 = feet).
17 multiplied by 15 = 255. So, there are 255 square feet in that room.
