🧩 Example Calculation

Let’s say you want to carpet a living room that measures:

• Length: 15 feet
• Width: 12 feet
• Wastage: 10%
• Carpet Price: $3.50 per sq.ft.

Here’s the Calculation:

1. Room Area = 15 × 12 = 180 sq.ft.
2. Wastage = 10% of 180 = 18 sq.ft.
3. Total Carpet Needed = 180 + 18 = 198 sq.ft.
4. Estimated Cost = 198 × $3.50 = $693.00

✅ Result: You’ll need approximately 198 square feet of carpet, costing around $693 including wastage.
