you need garden edging for a garden with a perimeter of 14m. garden edging comes in 1800mm length. how many length with you need to buy to have enough edging for the entire perimeter

To determine the number of garden edging lengths needed to cover the entire perimeter of a garden with a perimeter of 14 meters, we first need to convert the measurements to the same unit and then perform the calculation.

### Step 1: Convert Units
- The garden's perimeter is given as 14 meters.
- Garden edging comes in lengths of 1800 mm (millimeters).

Let's convert everything to meters:

\[
\text{1800 mm} = 1800 \div 1000 = 1.8 \text{ meters}
\]

### Step 2: Calculate the Number of Lengths Needed
Now, divide the total perimeter by the length of one garden edging:

\[
\text{Number of lengths needed} = \frac{\text{Perimeter}}{\text{Length of each edging}}
\]

\[
\text{Number of lengths needed} = \frac{14 \text{ m}}{1.8 \text{ m}}
\]

\[
\text{Number of lengths needed} \approx 7.78
\]

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

\[
\text{Number of lengths to buy} = 8
\]

### Conclusion
You need to buy **8 lengths** of garden edging to cover the entire 14-meter perimeter of your garden.
