Carpet Area Formula

The following two example problems outline the steps and information needed to calculate the Carpet Area.

CA = BA × .70
  • Where CA is the Carpet Area (ft^2)
  • BA is the total built-up area (ft^2) 

To calculate the carpet area, multiply the built-up area by .70.

How to Calculate Carpet Area?

The following example problems outline how to calculate Carpet Area.

Example Problem #1:

  1. First, determine the total built up area (ft^2).
    • The total built up area (ft^2) is given as: 1000.
  2. Finally, calculate the Carpet Area using the equation above: 

CA = BA * .70

The values provided above are inserted into the equation below and computed.

CA = 1000 * .70 = 700 (ft^2)


Example Problem #2: 

For this problem, the variables required are provided below:

total built up area (ft^2) = 2000

Test your knowledge using the equation and check your answer with the calculator..

CA = BA * .70 = ?
