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)
10 yards each yard has 3 feet so 10 yards is 30 feet which is greater than 20 feet
20 yards in 60 feet
60 feet are 20 yards.
20 feet is 6.67 yards.
20 yards = 60 feet
20 yards x 3 feet (in a yard) = 60 feet 60 feet are in 20 yards
60 yards is equivalent to 180 feet - as there are 3 feet in every yard.
20 yards.
20 yards.
6.66 yards.
20' x 10' (200 square feet) = 22.22 square yards.
20 yards is 60 feet.
