Raina is fertilizing her garden. The garden is in the shape of a rectangle. Its length is
15 feet and its width is 13
feet. Suppose each bag of fertilizer covers 39
square feet. How many bags will she need to cover the garden?
First multiply 260*180 to see how much square feet it covers. 260*180=46800 Then divide by 3000 46800/3000=15.6 But you can't buy 15.6 bags so you round up the 6.
