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 you'll need, follow these steps:

1. **Convert the garden edging length from millimeters to meters:**
   - The edging comes in **1800 mm** lengths.
   - Since 1000 mm = 1 meter, divide 1800 by 1000 to convert to meters:
     \[
     1800 \, \text{mm} = \frac{1800}{1000} = 1.8 \, \text{meters}
     \]

2. **Divide the garden perimeter by the length of one piece of edging:**
   - The garden perimeter is **14 meters**.
   - Now, divide the total perimeter by the length of one piece of edging:
     \[
     \frac{14}{1.8} \approx 7.78
     \]

3. **Round up to the nearest whole number:**
   - You can't buy a fraction of a length, so round **7.78** up to the next whole number, which is **8**.

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