🔍 Example: Rectangle Room (Flooring)
Suppose you have a rectangular room that is 12 ft wide and 15 ft long. You want to find the total square footage for flooring.
- Choose Shape = Rectangle
- Set Units = Feet (ft) and Area Unit = Square Feet (ft²)
- Enter Width = 12 and Length = 15
- Click Calculate Area
Formula: Area = Length × Width
⇒ Area = 15 × 12 = 180 ft²
If you enter a unit price (e.g., $2.50 per ft²), the calculator will also show:
Total Cost = 180 × 2.50 = $450.00.
