To calculate square feet, follow these steps:
- Measure the length and width of the area in feet. If your measurements are in feet and inches, convert the inches to feet by dividing by 12 and add that to the feet measurement.
- Multiply the length by the width to get the area in square feet:
Square Feet=Length (ft)×Width (ft)\text{Square Feet}=\text{Length (ft)}\times \text{Width (ft)}Square Feet=Length (ft)×Width (ft)
For example, if a room is 12 feet long and 20 feet wide, the square footage is:
12×20=240 square feet12\times 20=240\text{ square feet}12×20=240 square feet
This method works for rectangular or square areas. For a square, just multiply one side by itself. For irregular shapes like triangles or circles, use specific formulas:
- Triangle: 12×base×height\frac{1}{2}\times \text{base}\times \text{height}21×base×height
- Circle: π×radius2\pi \times \text{radius}^2π×radius2 (where π≈3.14\pi \approx 3.14π≈3.14)
If the space is complex (e.g., L-shaped), break it down into smaller shapes, calculate each area separately, then add them together to get the total square footage
. In summary:
- Measure length and width in feet.
- Multiply length by width for rectangles/squares.
- Use appropriate formulas for other shapes.
- Add areas for complex spaces.
This will give you the total square footage of the area.
