18 and two thirds square yards
To convert square feet to square yards, you need to divide by 9, since there are 9 square feet in a square yard. A 10' x 10' room is 100 square feet in total. Dividing 100 by 9 gives you approximately 11.11 square yards in a 10' x 10' room.
15 ft * 13 ft = 5 yd * 41/3 yard = 212/3 square yards
Remember there are 9 sq ft. in 1 sq. yard. Hence 10 ft x 12 ft = 120 sq. ft. Divide by '9' 120 / 9 = 13 3/9 sq yds. = 13 1/3 sq yds = 13.333... sq yds.
