🧮 Example: Calculating Carpet for a Living Room

Let’s take a practical example:

• Room Length: 15 feet
• Room Width: 12 feet
• Wastage: 10%
• Carpet Price per sq.ft.: $4.00

Step 1: Calculate Room Area

Area = Length × Width = 15 × 12 = 180 sq.ft.

Step 2: Add Wastage

10% of 180 = 18 sq.ft.
Total Carpet Needed = 180 + 18 = 198 sq.ft.

Step 3: Calculate Total Cost

198 sq.ft. × $4.00 = $792.00

✅ Result:
You’ll need 198 sq.ft. of carpet, and the total estimated cost will be $792.

This ensures you buy enough material without overspending or running short during installation.
