Finding square footage is all about calculating the area of a space.

Here's how to do it:

For a rectangular area:

- Measure the length and width: You'll need a measuring tape to accurately measure the longest side (length) and the shortest side (width) of the area in feet.
- Multiply length by width: Once you have the length and width in feet, simply multiply these two numbers together. This formula applies to any rectangular space, like a room or a floor.

Here's the formula in short:

- Length (ft) x Width (ft) = Area (sq ft)

For example, if your room is 12 feet long and 10 feet wide, the area would be 12 ft x 10 ft = 120 sq ft.

For oddly shaped areas:

If you're dealing with a more complex shape, you might need to break it down into rectangles and squares. Calculate the area of each individual shape using the rectangle formula, and then add all those areas up to get the total square footage.

There are also formulas for calculating the area of other shapes like triangles or circles, but for most common household spaces, the rectangle method will do the trick.
