Question

A square has an area of 64 square feet.

What is the length of each side of the square?

Correct me if I'm wrong but my answer is:

`√(64) = 8`
​

Answer 1

Explanation:

No you are correct. That's the correct end result. Technically you should start with

Area = s^2

Area = 64 ft^2

s^2 = 64

sqrt(s^2) = sqrt(64)

s = 8

s = - 8 has no meaning.

Your way is fine.
