💡 Practical Example

Let’s assume you’re carpeting your living room.

  • Room Length: 15 feet
  • Room Width: 12 feet
  • Wastage: 10%
  • Carpet Price: $3 per sq.ft.

Step 1: Room area = 15 × 12 = 180 sq.ft.
Step 2: Wastage = 10% of 180 = 18 sq.ft.
Step 3: Total carpet needed = 180 + 18 = 198 sq.ft.
Step 4: Estimated cost = 198 × $3 = $594

✅ Result: You’ll need 198 sq.ft. of carpet and a budget of $594.
