1. What is Square Feet Calculation?

Square feet calculation is a fundamental measurement used to determine the area of a two-dimensional space. It's commonly used in real estate, construction, and interior design to measure room sizes, flooring requirements, and property areas.

2. How Does the Calculator Work?

The calculator uses the simple area formula:

\[ \text{Square Feet} = \text{Length} \times \text{Width} \]
