Bob wants to start a lawn in an area that is 110ft by 70ft. One bag of seed covers 1200 square feet. How many bags should he buy?
Please help me solve
To find the area, multiply:
110 * 70 = 7700 square feet
Divide 7700 by 1200 to find the number of bags.
Remember that you can't buy part of a bag -- so you'll need to round up to the nearest whole number.
5 bags?
The lawn is a rectangular area of 110 ft by 70 ft. Can you find tha area (A) of the lawn?
Now each bag covers 1200 sq.ft, so how many bags are required? You divide the area A by 1200.
If you go into my gardening shop and ask for 3.54 bags, I will sell you 4 bags, get the idea?
Write again if you could use some more help, or check your answer.
Try again Claire. Use a calculator if you need to.
To determine how many bags of seed Bob should buy to cover his lawn, we need to calculate the area of the lawn and then divide it by the coverage area of one bag of seed.
First, let's find the area of Bob's lawn. The area of a rectangle is calculated by multiplying its length by its width. In this case, the length of the lawn is 110 feet, and its width is 70 feet. So, the area of Bob's lawn is:
Area = Length * Width
Area = 110 ft * 70 ft
Area = 7700 square feet
Now that we know the area of the lawn is 7700 square feet, we can determine how many bags of seed Bob should buy. Since one bag of seed covers 1200 square feet, we can divide the lawn's area by the coverage area of one bag of seed:
Number of bags = Area of lawn / Coverage area of one bag of seed
Number of bags = 7700 square feet / 1200 square feet
Number of bags ≈ 6.42 bags
Since we can't buy a fraction of a bag, Bob should round up to the nearest whole number. Therefore, Bob should buy 7 bags of seed to cover his lawn.
