Xiang needs to purchase 20 bags of grass seed to cover his backyard.
Step-by-step explanation:
To find the number of bags of grass seed Xiang needs to purchase, we need to divide the area of his backyard by the coverage of one bag of grass seed.
Given that each bag covers 54 square yards and Xiang's backyard has an area of 1064 square yards, we can use the formula:
Number of bags = Area of backyard / Coverage per bag
Substituting the values:
Number of bags = 1064 / 54
Number of bags ≈ 19.70 (rounded to the nearest whole number)
Therefore, Xiang would need to purchase 20 bags of grass seed to cover his backyard.
The probable question can be: Each bag of grass seed covers 54 square yards. How many bags of grass seed will xiang need to purchase to cover his backyard of 1064 yard square.
