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 find out how many garden edging lengths you will need:

1. The total perimeter of the garden is 14 meters.
2. Each garden edging length is 1800 mm, which is 1.8 meters (since 1000 mm = 1 meter).

Now, divide the perimeter by the length of one edging piece:

\[
\frac{14 \, \text{meters}}{1.8 \, \text{meters per length}} = 7.78
\]

Since you cannot buy a fraction of an edging piece, you will need to round up to the nearest whole number. Therefore, you will need **8 lengths** of garden edging to cover the entire perimeter.

Would you like more details on this solution or have any questions?

Here are 5 related questions to think about:
1. How would the number of lengths change if the perimeter were 20 meters?
2. What if each length was 2 meters instead of 1.8 meters?
3. How many meters of edging would be left over after using the 8 lengths?
4. How would the solution change if the perimeter was measured in centimeters?
5. How could you cut the 8th length to fit the exact perimeter?

**Tip:** When solving real-life measurement problems, always round up when the product involves physical objects that can't be split easily.
