📏 Formula Behind the Calculator
The Carpet Replacement Calculator uses a simple mathematical formula:
Total Area (sq.ft) = Length (ft) × Width (ft)
Total Cost ($) = Total Area (sq.ft) × Cost per sq.ft
Example:
Let’s say:
- Room Length = 12 ft
- Room Width = 10 ft
- Carpet Cost = $2.50 per sq.ft
Total Area = 12 × 10 = 120 sq.ft
Total Cost = 120 × 2.5 = $300
So, you’ll need 120 sq.ft of carpet and the total cost will be $300.
