Question

each side of a square office is 21 feet long. it will cost $5.00 per square foot to replace the carpet in the office. what would be the total cost to replace the carpet?

Explanation:

Step1: Calculate the area of the square office

The area formula for a square is \(A = s^2\), where \(s\) is the side - length. Given \(s = 21\) feet, then \(A=21\times21=\$441\) square feet.

Step2: Calculate the total cost

The cost per square foot is \(\$5.00\). The total cost \(C\) is the product of the area \(A\) and the cost per square foot. So \(C = 5\times A\). Substitute \(A = 441\) into the formula: \(C=5\times441 = 2205\).

Answer:

\(2205\)
