Answer:
B) 18 bags
Step-by-step explanation:
Firstly,we need to find the area of only the vegetable garden.
Area of a rectangular garden is given by :
From the picture, it can be inferred that,
the dimension of the vegetable garden is:
24 by 9
This implies that,
Length=24 feet
Width=9 feet
Substituting this into the formula, we obtain
it is stated in the question that each bag of special fertilizer bag covers 12 square feet.
using ratio,
1 bag:12square feet
x bag:216squaure feet
This implies,
By cross multiplying , we obtain
Divide both sides by 12
Hence, it will take18 bags of the special fertilizer to
cover the vegetable garden.
