a back yard is shaped like a parallelogram with a height of 32 feet and a base of 100 feet. One bag of grass seed covers 125 square feet. What is the least number of bags of seed needed to seed the lawn?
Also, please explain how you got it.
A = b * h
A = 100 * 32
A = 3200 sq. feet
3200 / 125 = 25.6
You'll need 27 bags of seed.

25.6
27 bags
if you could i would ask you if you can please answer asap because i have tons of homework tonight
To find the least number of bags of grass seed needed to seed the lawn, you first need to calculate the area of the backyard.
The formula for the area of a parallelogram is:
Area = base * height
In this case, the base of the backyard is 100 feet and the height is 32 feet. So the area is:
Area = 100 feet * 32 feet = 3200 square feet
Now, you need to determine how many bags of grass seed are needed to cover this area. Given that one bag of grass seed covers 125 square feet, you divide the total area by the area covered by one bag of seed:
Number of bags = total area / area covered by one bag
Number of bags = 3200 square feet / 125 square feet ≈ 25.6
Since you cannot have a fraction of a bag, you need to round up to the nearest whole number. Therefore, you will need at least 26 bags of grass seed to seed the lawn.
Explanation Recap:
1. Calculate the area of the backyard: Area = base * height = 100 feet * 32 feet = 3200 square feet.
2. Divide the total area by the area covered by one bag of seed: Number of bags = 3200 square feet / 125 square feet ≈ 25.6.
3. Round up to the nearest whole number: You will need at least 26 bags of grass seed.
