Question:

The area of a square is 9m² + 12m + 4. Find the measure of the side of the square.

Options:

3m + 2

3m + 4

3m² + 2

3m² + 2m

Correct Answer:

3m + 2

Explanation:

We know that,

The area of the square = (side)²

We know,

The area of the square = 9m² + 12m + 4

From the formula a² = 9m² + 12m + 4

= a² = (3m + 2)²

= a = 3m + 2
