Numeracy question. 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?
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 follow these steps:

1. **Convert the perimeter to millimeters**:  
   Since 1 meter = 1000 millimeters, a perimeter of 14 meters is:
   \[
   14 \, \text{m} = 14 \times 1000 = 14,000 \, \text{mm}
   \]

2. **Determine the length of each garden edging in millimeters**:  
   Each piece of garden edging is 1800 mm long.

3. **Calculate how many pieces are needed**:  
   Divide the total perimeter by the length of each piece of edging:
   \[
   \frac{14,000 \, \text{mm}}{1800 \, \text{mm}} \approx 7.78
   \]

4. **Round up to the nearest whole number**:  
   Since you can't buy a fraction of a piece, round up 7.78 to 8.

You will need to buy **8 lengths** of garden edging to cover the perimeter of 14 meters.

Here are 5 related questions to explore further:
1. How would the number of lengths change if the perimeter were 16 meters instead?
2. What is the cost of the garden edging if each piece costs $12?
3. How much leftover edging would you have after covering the 14-meter perimeter?
4. If each length of edging can be cut, how much of the last length would need to be trimmed to fit the perimeter exactly?
5. How many lengths would be required for a garden with a perimeter of 28 meters?

**Tip:** When solving problems involving measurements, always convert units to the same system (e.g., meters to millimeters) before performing calculations.
