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 calculate how many lengths of garden edging you need, we can break the problem down like this:

1. **Convert the perimeter to millimeters**:  
   Since the garden edging comes in millimeters (1800 mm), first convert the garden's perimeter from meters to millimeters.  
   \[
   14 \, \text{m} = 14,000 \, \text{mm}
   \]

2. **Divide the perimeter by the length of each edging strip**:  
   Now, divide the total perimeter (14,000 mm) by the length of one edging strip (1800 mm).  
   \[
   \frac{14,000 \, \text{mm}}{1800 \, \text{mm/length}} = 7.78
   \]

3. **Round up to the nearest whole number**:  
   Since you can't buy a fraction of a length, you will need to round up.  
   \[
   7.78 \approx 8
   \]

So, you will need to buy **8 lengths** of garden edging.
