a rectangle plot of land is to be seeded with grass if the plot is 22m x 28m and 1 kg bags of seed is needed for 85 m2 of land how many bags of seed are needed
22 * 28 = 616 sq. meters
616 / 85 = ?
616/85=7.24 bags needed
Right. But stores won't sell you 0.24 of a bag -- so you must buy 8 bags.
so my answer shoud be 8?
Strictly speaking, since your problem asks how many bags you need, 7.24 is the correct answer.
ok thanks did you see the distance question I posted?
To find out how many bags of seed are needed, you need to calculate the area of the rectangle plot of land and then divide it by the amount of land that can be covered by 1 kg bag of seed.
Step 1: Calculate the area of the rectangle plot of land.
The area of a rectangle can be calculated by multiplying its length by its width.
Area = Length x Width
Area = 22m x 28m
Area = 616m²
Step 2: Calculate the number of bags of seed needed.
Now, divide the total area of the plot by the area covered by 1 kg bag of seed.
Number of Bags = Area of Plot / Area covered by 1 kg bag of seed
Area covered by 1 kg bag of seed = 85m²
Number of Bags = 616m² / 85m²
Number of Bags ≈ 7.25
Since you can't have a fraction of a bag, you would need to round up to the nearest whole number. Therefore, you would need 8 bags of seed to cover the entire plot.
So, 8 bags of seed are needed.
