The floor area ratio is calculated by taking the square footage of a building and dividing it by the square footage of the property that the building sits on. The floor area ratio is useful to local governments in showing the density of a property or area for zoning decisions.
Continue ReadingThe square footage of the building includes all floors of the structure when calculating the floor area ratio. For example, a two-story building of 3,000 square feet on a 4,000-square-foot lot has a ratio of 0.75. The same lot with a single-story building of 3,000 square feet would have the same ratio of 0.75.

Geometric formulas are derived from a similar need but applied to a geometric sequence with a common ratio of r, such as "an = a1 * r^(n - 1)."
Full Answer >A true proportion is a mathematical equation which states that one ratio is equal to another. A true proportion will often be written in the following format: a:b = x:y in which the ratio between a and b is equal to the ratio between x and y.
Full Answer >The value of y in the linear interpolation equation is defined as a sum of y0 and the product of y differential (y1 – y0), multiplied by the ratio between differentials of x ((x – x0) divided by (x – x1)). This is a method of calculating the unknown value of y for any given x on the interval between two known points with coordinates (x0,y0) and (x1,y1).
Full Answer >The golden ratio is often used to provide pleasing composition in art, architecture and design. The Great Pyramid of Giza, the Parthenon and many of the paintings created by Leonardo da Vinci are among the most famous examples of the use of the golden ratio.
