Question

The area of a square is x^2 − 6x + 9 sq. units. Find its perimeter.​

Answer 1

Answer:

$4 |(x - 3)| \: \: \: units.$

Step-by-step explanation:

$area = {x}^{2} - 6x + 9 \\ = {(x - 3)}^{2} \\ \\ side = \sqrt{area} \\ \\ side = \sqrt{ {(x - 3)}^{2} } \\ \\ side = |x - 3| \\ \\ perimeter = 4 \times side \\ \\ = 4 \times |x - 3|$
