Kennath's back yard is in the shape of a rectangle with a length of 12 yards and width of 10 yards. A bag of grass seed costs $25.99 and covers 400 square feet. How much will Kenneth spend on grass seed to cover his back yard?
Area = l x w. 12 yards x 10 yards=120 sq. yards. If the rest of the sentence is square yards, then one bag of seed will cover 400 sq. yards and it will cost him $25.00.
