Calculate Square Area: Finding Area When Side Length is 8 Units

To determine the area of a square with a side length of 8, we use the formula for the area of a square:

• $\text{Area} = \text{side length}^2$

Let's perform the calculations step by step:
The side length given is 8. Substituting this value into the formula, we have:
$\text{Area} = 8^2$

Calculating $8^2$, we find:
$8 \times 8 = 64$

Thus, the area of the square is $64$.

Therefore, the solution to the problem is $64$. This result matches the correct choice provided, which is choice $64$.
