Allowable Area Increase Calculator

Formula

The formula to calculate the Allowable Area Increase (A_a) is:

\[ A_{a} = A_{b} \times \left(1 + \frac{P}{100}\right) \]

Where:

Allowable Area Increase (A_a): The maximum permissible expansion of a given area based on a specified percentage increase.
Base Area (A_b): The original area before any increase.
Increase Percentage (P): The percentage by which the base area is increased.
Significance: Ensures expansions are within acceptable limits, maintaining structural integrity, safety, and compliance with zoning laws.

Let's say the base area (A_b) is 100 square units and the increase percentage (P) is 20%. Using the formula:

\[ A_{a} = 100 \times \left(1 + \frac{20}{100}\right) = 120 \]

So, the Allowable Area (A_a) is 120 square units.
