Question

2 the area of a square is 66 m². about how many meters long is each side of the square?

Explanation:

Step1: Recall area formula for square

The area formula of a square is $A = s^{2}$, where $A$ is the area and $s$ is the side - length. Given $A = 66\ m^{2}$, we need to solve for $s$, so $s=\sqrt{A}$.

Step2: Calculate the square - root

$s=\sqrt{66}$. We know that $8^{2}=64$ and $9^{2}=81$. Since 66 is closer to 64, $\sqrt{66}\approx 8.124$. Rounding to the nearest whole number, $s\approx 8$ m.

Answer:

About 8 meters
