The square foot is a unit of area. The area could be of a rectangular surface, a circular surface or even a triangular surface.

The need to calculate the amount per square foot often arises in constructions. Building contractors need to know the cost per square foot to estimate total material costs and labor costs.

When renting an apartment, the ability to calculate the amount per square foot allows you to determine if you’re paying too much.

**Formula to calculate price per square foot.**

To calculate this, we divide the total cost by the total area.

**Example:**

A mason was to construct a floor of total area 500 ft² , if the total cost of the construction is Sh. 5,000, calculate the price per square foot.

Therefore, the price per square foot is Sh. 10.
