If it is a 17 yard by 9 yard room then 153 square yards!
12 square yards.
28 square yards.
About 13.3 square yards.
1 square yard = 9 square feet. so a room 12' x 13' = 156 sq ft or 17.333 square yards
21.33
25 square yards in a 15' x 15' room.
of course 12 square yard
Since there are 9 square feet in a square yard - the answer is 13 !
A 12' x 9' room has an area of 12 square yards.
There are 3 feet in 1 yard so 15 feet is equal to 5 yards. So a 15 feet by 15 feet room is a 5 yard by 5 yard room. 5 yards x 5 yards = 25 square yards.
A 12 yard * 10 yard room occupies 12*10 = 120 sq yards.
