ou 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 to buy, follow these steps:

1. **Convert the length of each garden edging** from millimeters to meters:  
   \( 1800 \, \text{mm} = 1.8 \, \text{m} \).

2. **Divide the total perimeter of the garden** by the length of one garden edging piece:  
   \( \frac{14 \, \text{m}}{1.8 \, \text{m}} = 7.78 \).

3. Since you cannot buy a fraction of a length, round up to the nearest whole number:  
   You will need to buy **8 lengths** of garden edging.

Here are some related questions:
1. What if the perimeter was 20 meters, how many lengths would you need?
2. How would you calculate if the edging came in 2000mm lengths?
3. How do you account for cutting or extra pieces in practice?
4. What if you had a circular garden, how would you calculate the edging required?
5. Can this method be applied to other shapes of gardens, like triangular ones?

**Tip:** Always round up when calculating items like edging to ensure you have enough for the full perimeter!
