Question

A square has an area of 9 cm^2. What is the length of each side?

Answer 1

3cm

Explanation:

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

`√(9)` = 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

Answer 2

The side length is 3 cm

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
