The question in the image asks, "What is the side length of the square?" and provides an area $A = 64 \, \text{in}^2$.

To find the side length $s$ of the square, you use the formula for the area of a square:

$A = s^2$

Given $A = 64 \, \text{in}^2$, we can solve for $s$ by taking the square root of both sides:

$s = \sqrt{64} = 8 \, \text{in}$

So, the side length of the square is $8 \, \text{in}$.

Here are 5 related questions for further exploration:

1. How would you calculate the side length if the area was 100 square inches?
2. What is the perimeter of a square with an 8-inch side length?
3. How do you find the area of a rectangle with different side lengths?
4. If the side length of a square is tripled, how does that affect the area?
5. What is the square root of a number, and how is it related to area?

Tip: When working with areas of squares, the side length is always the square root of the area!
