Question

1. relate the area of the square to the length of each side. a = 16 cm² side length side length cm × cm √16 =

Explanation:

Step1: Recall area formula for square

The area formula of a square is $A = s\times s$, where $s$ is the side - length. Given $A = 16\ cm^{2}$, we have $s\times s=16$.

Step2: Solve for side - length

To find $s$, we take the square root of both sides of the equation $s^{2}=16$. So, $s=\sqrt{16}$.

Answer:

4 cm × 4 cm
$\sqrt{16}=4$
