How Do You Determine Square Footage?

Square footage refers to measured area being expressed in terms of feet. Each foot is made up of twelve inches and each square foot is twelve inches by twelve inches in size; in other words a hundred and forty four square inches. Square feet measurements are usually found used in the realm of real estate, heating and cooling appliance capacities etc. The formulas for area calculation do not change even in case square feet are being used; the area of a square is still the square of its side, a triangles area is still ½×base×heigt and a circle is still measured as πr².

The only complication being that the area is usually expressed in some other unit of measure such as square meters or square centimetres etc. Each square foot is 0.0929 square meters, 929.0304 square centimetres, 92903.04 square millimetres etc.
