Answer:
He will need 7 bags of fertilizer to cover the whole garden.
Explanation:
Given:
Hans is fertilizing his garden which is in a shape of a rectangle.
The length of Hans garden is 14 feet and width 11 feet.
Suppose to fertilize the garden one bag of fertilizer covers 22 square feet.
Now, to find the number of bags he will need to cover the whole garden.
The garden's shape is rectangle.
And, the dimensions of garden are:
Length = 14 feet.
Width = 11 feet.
So, we find the area of garden by using formula:

Thus, the total area of garden is 154 square feet.
And, the area of garden each bag of fertilizer covers is 22 square feet.
Now, to get the number of fertilizer bags he will need to cover the total garden we divide the total area of garden by the area of garden each bag of fertilizer covers:

Hence, he will need 7 bags of fertilizer to cover the whole garden.
