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 complete the edging of the garden perimeter?

To determine how many 1800mm garden edging lengths are needed to cover a 14m perimeter, we can follow these steps:

1. **Convert 14 meters to millimeters**:
   \[
   14 \text{ m} = 14 \times 1000 = 14000 \text{ mm}
   \]

2. **Divide the total perimeter in millimeters by the length of each edging piece**:
   \[
   \frac{14000 \text{ mm}}{1800 \text{ mm}} \approx 7.78
   \]

Since you can't use a partial length of edging, you’ll need to round up to the next whole number.

3. **Round up to the nearest whole number**:
   \[
   8 \text{ lengths}
   \]

**Answer**: You will need **8 lengths** of 1800mm garden edging to cover the entire 14m perimeter.

Here are some related questions for further exploration:

1. How much extra length will you have if you buy 8 lengths?
2. How much would the total cost be if each length costs $5?
3. What if the perimeter was increased by 2m? How many lengths would be needed?
4. How many lengths would be needed if each edging piece was 1500mm instead?
5. If you had only 7 lengths, how much of the perimeter could you cover?

**Tip**: Always ensure units are consistent throughout a calculation for accuracy.

Determine how many 1800mm garden edging lengths are needed to cover a 14m perimeter. This solution guides you through unit conversion, division, and rounding to find you’ll need 8 lengths for full coverage. Perfect for Grade 5-6 students learning practical math.
