If it's a rectangle, then the area = (12 x 7) = 84 square feet = 9 and 1/3 square yards
Ah, what a delightful question! To find the area of a square, you simply multiply the length of one side by itself. So, if the sides of the square are 7 yards long, you would multiply 7 by 7 to get an area of 49 square yards. Isn't that just lovely?
7 * 8 = 56 ■
7 feet 2(7+2) = 18 feet 7*2 = 14 square feet
18 x 7 = 126 square feet
7' x 7' (49 square feet) = 5.44 square yards.
square yards x 3.228306e-7 = square miles
There are 9 sq feet in a square yards. So this means it is 64 square feet.
18 feet is 6 yards, and 21 feet is 7 yards. 6 multiplied by 7 is 42. Therefore, it's 42 square yards.
9.33... sq yards
5 ft*7ft = 5/3 yards*7/3 yards = 35/9 square yards = 3.88... sq yards.
7*5 = 35 square yards
If a room is 10 feet by 21 feet then its area = 10 * 21 = 210 square feet. There are 3 feet in a yard. There are therefore 3 * 3 = 9 square feet in a square yard. Thus to convert we now divide by 9.Therefore this is 210/9 = 23 1/3 square yards.Alternatively, and if you prefer, you can convert your measurements first. As there are 3 feet to a yard then 10 feet = 10/3 = 3 1/3 yards. 21 feet = 21/3 = 7 yards.3 1/3 * 7 = 23 1/3 square yards.
7' But to convert it, simply multiply 2 1/3 by 3. Then you will get 7 feet.
There is more than one way to work this out, here is an example, multiply 7 feet by 10 feet to get the answer in square feet, in this case it's 70 square feet, there are 9 square feet in a square yard, so divide 70 by 9 to get the answer, which is approx 7.78 square yards (7.77777778 square yards exactly)
63... since there are 9 square feet in a square yard.
21 square feet EZ
