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 find out how many lengths of garden edging you need, follow these steps:

1. **Convert the length of one garden edging strip to meters**:
   \[
   1800 \, \text{mm} = 1.8 \, \text{m}
   \]

2. **Divide the total perimeter by the length of one strip**:
   \[
   \frac{14 \, \text{m}}{1.8 \, \text{m}} \approx 7.78
   \]

Since you can't buy a fraction of a length, you need to round up to the nearest whole number.

3. **Round 7.78 up to 8**.

Therefore, you will need to buy **8 lengths** of garden edging to cover the entire perimeter.

1. What if the garden perimeter was 20 meters instead of 14?
2. How much total edging would you have if you bought 8 lengths?
3. If one length costs $15, how much will the total cost be?
4. What would the perimeter be if you only had 6 lengths of edging?
5. How many lengths would you need if each length was 2 meters long?

**Tip:** When working with measurements, always make sure units are consistent before performing calculations!
