You need garden edging for a garden with a perimeter of 14m. Garden edging comes in 1800mm lengths. How many lengths will you need to buy to have enough edging for the entire perimeter?




To determine how many lengths of garden edging you'll need:

1. First, convert the 1800mm length to meters:
\[
1800 \, \text{mm} = \frac{1800}{1000} = 1.8 \, \text{m}
\]

2. Now, divide the total perimeter of the garden by the length of each edging piece:
\[
\frac{14 \, \text{m}}{1.8 \, \text{m}} = 7.78
\]

Since you can't purchase a fraction of an edging piece, you'll need to round up:
\[
\lceil 7.78 \rceil = 8
\]

Therefore, you will need to buy **8 lengths** of garden edging.

Here are 5 related questions:
1. What would the cost be if each length of edging is priced at a certain amount?
2. What if the perimeter was 20m instead of 14m?
3. How would the number of lengths change if each piece of edging was 2 meters long instead?
4. How can you calculate the total area of the garden based on its shape?
5. What if you had irregular edges—how would you account for the extra edging needed?

**Tip:** Always round up when calculating quantities for physical items like garden edging to ensure you have enough!
