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 need, follow these steps:

1. **Convert the perimeter to millimeters**:  
   Since the edging is measured in millimeters, convert the perimeter from meters to millimeters.  
   $ 14 \, \text{m} = 14,000 \, \text{mm} $.

2. **Calculate how many 1800 mm lengths are needed**:  
   Divide the total perimeter by the length of one garden edging strip.  
   $ \frac{14,000 \, \text{mm}}{1800 \, \text{mm}} = 7.78 $.

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

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