Answer:

The side length is 3 cm

Step-by-step explanation:

The area of a square is given by

A = s^2  where s is the side length

9 = s^2

Take the square root of each side

sqrt(9) = sqrt(s^2)

3 =s

The side length is 3 cm

Answer:

3cm

Step-by-step explanation:

As we know it's a square, we can just square the area to get:

[tex]\sqrt{9}[/tex] = 3

We know we can do this as to find the area of a square or rectangle you just need to multiply the sides together. As it's a square, all the sides are the same so they have the formula:

x * x = A (unit)^2
