a bag of fertilizer claims that it will cover 5000 square feet of grass if you front yard is 1450- feet wide and 65 feet deep and you back yard is 150 feet wide and 225 feet deep how many bags of fertilizer will you nee to fertilize your entire back yard?
Determine the area in each of the yards, add them together, then divide by the coverage per bag.
The area of a rectangle is the width times the depth.
To find out how many bags of fertilizer you will need to fertilize your entire backyard, follow these steps:
1. Calculate the area of your backyard by multiplying the width (150 feet) by the depth (225 feet):
Area of backyard = Width × Depth
Area of backyard = 150 feet × 225 feet
Area of backyard = 33,750 square feet
2. Determine the coverage area of one bag of fertilizer. According to the claim on the bag, one bag covers 5,000 square feet.
3. Divide the total area of your backyard by the coverage area of one bag to find the number of bags you will need:
Number of bags needed = Total area ÷ Coverage area
Number of bags needed = 33,750 square feet ÷ 5,000 square feet
Number of bags needed ≈ 6.75
Since you cannot have a fraction of a bag, you will need to round up to the nearest whole number. This means you will need to purchase 7 bags of fertilizer to cover your entire backyard.
