Question

relate the area of the square to the length of each side. a = 9 cm² side length × side length = √9 cm

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^2$, where $A$ is the area and $s$ is the side - length.

Step2: Solve for side - length

Given $A = 9\ cm^2$, we have $s^2=9$. Taking the square root of both sides, $s=\sqrt{9}$. Since the side - length of a square cannot be negative in this context, $s = 3\ cm$. So the side - length $\times$ side - length $=3\ cm\times3\ cm=\sqrt{9}\ cm\times\sqrt{9}\ cm$.
