# How Do You Figure Out the Square Footage of an Area?

To figure out the square footage of an area, one must first measure the sides of the area or the diameter of the area if the area is round. Then, depending on the shape of the area, the appropriate formula must be applied to determine the square footage.

For rectangles and squares, after the length and width are measured, the length and width are then multiplied together to obtain the square footage. For a triangle, the base and height are measured, and then the base and height are multiplied by one-half. Note that for triangles, any side of the triangle can be considered the base for measurement purposes.

For circles, after the diameter is measured, the diameter is divided by two to get the radius, and then the radius is multiplied by 3.14 to determine the square footage. For an irregular space, the space is split into known shapes and then measured accordingly.
