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 length of one piece of garden edging to meters**:
   \[
   1800 \, \text{mm} = 1.8 \, \text{m}
   \]
   
2. **Divide the total perimeter by the length of one piece**:
   \[
   \frac{14 \, \text{m}}{1.8 \, \text{m}} = 7.78
   \]

3. Since you can't buy a fraction of a piece, you'll need to round up to the nearest whole number:
   \[
   \lceil 7.78 \rceil = 8
   \]

Thus, you need to buy **8 lengths** of garden edging to cover the entire 14-meter perimeter.

2. If the garden edging length was 2000mm, how many pieces would you need for the same 14m perimeter?
3. What if the edging pieces were 1.5m instead of 1.8m? How many would you need for a 14m perimeter?
