35 square yards
25 square yards in a 15' x 15' room.
To measure square yards in a room, first, determine the area in square feet by multiplying the length and width of the room. In this case, for a 15x20 room, the area would be 300 square feet. To convert square feet to square yards, divide the total square footage by 9 (since 1 square yard is equal to 9 square feet). Therefore, a 15x20 room would be 33.33 square yards (300 square feet divided by 9).
A 12 by 15 room: 12 x 15 = 180 180 divided by 9 = 20 (one yard is 9 square feet) So, depending on the room, you might need 20 to 21 yards of carpet for a 12 by 15 room. John
15 x 20 is 300 square feet or 100 square yards.
15 square yards = 135 square feet.
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.
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.
You have to multiply the two dimensions to get the area. In this case the answer will be 450 square feet. Divide by 9 to get 50 square yards.
Convert measurements to yards and then multiply them
15' x 15' (225 square feet) = 25 square yards.
Multiply the two dimensions to get the area. The calculation will give you 170.5 square feet which converts to 18.94 square yards.
