Answer:
50 packs of seed
Explanation:
The back yard is a rectangle
Length is 28 ft
Width is 25 ft
The area of a rectangle is equal to the length times the width
area = length * width
So plugging in our numbers
area = 28 ft * 25 ft
area = 700 sqft
sqft means square feet or ft^2
We know each pack of seeds will cover 14 sqft, so the question is, how many times does 14 go into 700?
number of packs = 700 sqft / 14 sqft per pack
number of packs = 50 packs
