Answer 2

Answer:

8 cm

Step-by-step explanation:

Because A=a*a

Area equals length times length

So, 8 is the length

64 divided by some number must equal the exact same number. Let me show what I am talking about.

Our length is a. We multiply a times itself (because that's the formula for the square's area)

Does this number exist?

Yes, it does.

And it's a whole number.

And we know from our times tables that 8*8=64
