The area of a square is 9 square centimeters. How long is one side?

Assuming the side length = 9 cm:

A = s^2

A = 9^2 = 81 cm^2

Step-by-step explanation:

3 centimeters (not squared!)

Step-by-step explanation:

Area = lw

You can find it using this formula:

a = √A

A = √9

You would get 3 as your answer.

You can also think of it like this:

Area of a square = lw

What two numbers multiplied together get you 9?

3 x 3 = 9

Hope this helps.

Also, it's just a side length, so don't square it! :)

question:

could we have options?

i believe the correct answer is b.
