**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 are required, we need to divide the total perimeter of the garden by the length of one piece of garden edging.

1. **Total perimeter**: 14 meters
2. **Length of one garden edging piece**: 1800 mm = 1.8 meters

Now, divide the total perimeter by the length of one edging piece:

\[
\frac{14 \, \text{meters}}{1.8 \, \text{meters per piece}} = 7.78
\]

Since you can't buy a fraction of a length, you will need to round up to the nearest whole number. Therefore, you'll need 8 lengths of garden edging to cover the perimeter.

**Answer**: You will need to buy 8 lengths of garden edging.

Do you want more details on this solution, or do you have any questions? Here are 5 related questions for practice:

1. If the garden perimeter was 20 meters, how many lengths would you need?
2. What is the total length of garden edging required if the perimeter is 25 meters?
3. How many pieces would you need if each garden edging length was 1500 mm?
4. What would be the total cost if each piece costs $10 and you need 8 pieces?
5. If you only bought 7 lengths, how much of the perimeter would remain uncovered?

**Tip**: Always convert units (mm to meters or vice versa) before doing calculations to avoid confusion.
