Question

the area of the square is square centimeters.

Explanation:

Step1: Use the formula for the area of a square

The formula for the area of a square is \(A = s^2\), where \(s\) is the side - length of the square.

Step2: Substitute the value of the side - length

Given \(s = 9\) cm. Then \(A=(9\mathrm{cm})^2\).

Step3: Calculate the result

\(A = 9\times9\mathrm{cm}^2=81\mathrm{cm}^2\)

Answer:

\(81\)
