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?

The garden edging comes in lengths of 1800mm, which is 1.8 meters (since 1800mm = 1.8m). To determine how many lengths you need, divide the total perimeter of the garden (14 meters) by the length of one piece of edging (1.8 meters):

\[
\frac{14}{1.8} = 7.78
\]

Since you can't buy a fraction of a length, you'll need to round up to the nearest whole number. Therefore, you'll need 8 lengths of garden edging to cover the entire perimeter.

Would you like further details or have any other questions?

Here are 5 related questions:
1. How would the calculation change if the perimeter was 20 meters instead of 14 meters?
2. What if the garden edging came in 2.5-meter lengths?
3. How many lengths would you need for a garden perimeter of 25 meters?
4. How can you estimate the cost if each length costs $12?
5. How would the total change if you needed to add a 1-meter gate to the garden?

**Tip:** Always convert all units to the same system (e.g., meters) before performing calculations to avoid errors.

Find out how many lengths of garden edging you need for a garden with a 14-meter perimeter, with each length of edging measuring 1800mm. Learn to convert units and divide to calculate the correct number of pieces, including rounding up to ensure full coverage. Ideal for students in Grades 6-8.
