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 how many 1800mm garden edging lengths are needed for a garden with a perimeter of 14 meters, we first need to convert all units to the same measurement (millimeters or meters).

1. **Convert 1800mm to meters**:
   \[
   1800 \, \text{mm} = 1.8 \, \text{m}
   \]

2. **Divide the perimeter by the length of each garden edging**:
   \[
   \frac{14 \, \text{m}}{1.8 \, \text{m}} \approx 7.78
   \]

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

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

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

1. What if the garden's perimeter were 20m instead of 14m?
2. How many lengths would you need if the edging came in 2m lengths?
3. What is the total cost if each length costs $15?
4. How much extra length would you have if you purchased 8 lengths?
5. How would the number of lengths change if the perimeter were increased by 2m?

**Tip:** Always round up when dealing with physical objects to ensure you have enough material.
