Answer:
8
Step-by-step explanation:
The area of a square is equal to its length times its width. Or l * w.
Since squares are equal on all sides, this can simply be written as 2s=a.
So, rewrite the equation to be 2s=64.
Divide by 2 on both sides and s=8.
Thereforer the length of each side is 8.
the only 2 possible answers are 2 and -2 .But the answer is y=2 because x is positive
