Numeracy question. 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?
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 perimeter to millimeters**:  
   Since the perimeter is given in meters and the garden edging is in millimeters, we convert 14 meters into millimeters:
   \[
   14 \, \text{m} = 14,000 \, \text{mm}
   \]

2. **Determine how many 1800mm lengths fit into 14,000mm**:  
   Now, divide the total perimeter by the length of each garden edging piece:
   \[
   \frac{14,000 \, \text{mm}}{1,800 \, \text{mm}} = 7.78
   \]

3. **Round up to the nearest whole number**:  
   Since you can't buy a fraction of a length, round up to the nearest whole number:
   \[
   \text{You need} 8 \text{ lengths of garden edging.}
   \]

### Final Answer:  
You will need to buy **8 lengths** of garden edging.
