👉 Formula used: Square Footage=Length (ft)×Width (ft)\text{Square Footage} = \text{Length (ft)} \times \text{Width (ft)}Square Footage=Length (ft)×Width (ft)
For multiple rooms: Total Square Footage=∑(Length×Width for each room)\text{Total Square Footage} = \sum (\text{Length} \times \text{Width for each room})Total Square Footage=∑(Length×Width for each room)
Practical Example
Imagine you want to calculate the size of a house with three main areas:
- Living Room: 20 ft × 15 ft = 300 sq ft
- Kitchen: 12 ft × 10 ft = 120 sq ft
- Bedroom: 15 ft × 14 ft = 210 sq ft
Total Square Footage = 300 + 120 + 210 = 630 sq ft
This way, you can quickly estimate the size of your home or any section of it with accuracy.
