Multiple Choice Question

A square has an area of 9 square centimeters. What is its side length?

A.

B.

C.

D.

To find the side length of a square given its area, we use the formula for the area of a square:

\[
\text{Area} = \text{side length}^2
\]

In this case, the area is given as 9 square centimeters, so we have:

\[
\text{side length}^2 = 9
\]

Taking the square root of both sides:

\[
\text{side length} = \sqrt{9} = 3 \, \text{cm}
\]

So the side length of the square is **3 centimeters**.

If you want to include this in a multiple-choice format, the correct answer would be:

**D. 3 cm**
