Which answer is it? I just learned this today, so I'm confused.

Answer:
H. [tex]\sqrt{32}[/tex] = 5.7 inches
Step-by-step explanation:
1) Because you multiply the length and the width to get the area, you just need to find the square root of the area.
When you look for the square root of 32, it is 5.6....
Round up and you get 5.7 inches which s the length of one side.
Therefore, H. is the correct answer.
