Question

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

Answer 1

Answer: The side length is 3 yards.

Step-by-step explanation:

To find the area of a square, you have to square one of it's side lengths since they all share the same length.  Since we know the area, and we need to find the side length so we just need to find the square root of the area.

$\sqrt{9}$ = 3    

The side length is 3 yards.
