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 solve this problem, let's break it down step by step.

1. **Garden Perimeter**: The perimeter of the garden is 14 meters, which equals 14,000 millimeters (since 1 meter = 1,000 millimeters).
   
2. **Length of Garden Edging**: Each garden edging piece is 1,800 millimeters long.

3. **Number of Edging Lengths Needed**: 
   To find how many pieces of garden edging are required, divide the total perimeter by the length of one piece:
   \[
   \frac{14,000 \, \text{mm}}{1,800 \, \text{mm/piece}} = 7.78 \, \text{pieces}
   \]
   
   Since you can't buy a fraction of a piece, you'll need to round up to the nearest whole number. Therefore, you will need to buy **8 lengths** of garden edging.

Would you like more details or have any questions? Here are 5 related questions to further explore:

1. How much garden edging will be left after using 7 full pieces?
2. What is the total length in meters of 8 pieces of edging?
3. If the price of one edging piece is \$12, how much will it cost to buy 8 pieces?
4. What would happen if each edging length was 2000 mm instead of 1800 mm?
5. How many pieces of edging would be needed if the perimeter was 18 meters?

**Tip:** Always convert units to be consistent (like meters to millimeters) before performing calculations.

Learn how to calculate the number of garden edging lengths needed for a 14-meter perimeter. The problem involves unit conversion from meters to millimeters, dividing by the length of each edging piece (1800mm), and rounding to the nearest whole number. Suitable for students in Grades 5-7.
