There are 36 square yards in a room 18 feet by 18 feet
If the room is 18 FEET by 19 feet, the area of the room is 18 feet * 19 feet = 18/3 yards * 19/3 yards = 18*19/9 sq yards = 2*19 sq yards = 38 sq yards.
36 square yards.
28 * 18 / 9 = 56 square yards.
18' x 16' (288 square feet) = 32 square yards.
18 ft = 18 divided by 3= 6 yards so; 6 by 6 = 36 sq. yards
The answer depends on the measurement unis used for the numbers given in the question. It should be obvious to everyone that the number of square yards for a room which is 11.9 feet by 18 feet will be different to one for a room which is 11.9 yards by 18 yards.
1 square yard = 9 square feet 2 square yards = 18 square feet 3 square yards = 27 square feet . . . 24 square yards = 216 square feet
As there are 3 feet in a yard, the room measures 4 yards by 6 yards, so, 6 x 4 = the size of the carpet.
40 Square Yards and Usually you want some overage so about 44 yards.
you will need 84 sq. yards of wallpaper
24 square yards 12 feet is four yards and 18 feet is six yards, so four yards by six yards equals twenty four square yards.
6 yards is 18 feet.
