Question

find the area of this square. 9 m

Explanation:

Step1: Recall the formula for the area of a square

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

Step2: Substitute the side - length into the formula

Given that \(s = 9\space m\), then \(A=9\times9\).

Step3: Calculate the result

\(9\times9 = 81\).

Answer:

\(81\)
