Question

If the area is $\rm some ~random~ number$, then the length of the side is $\rm\sqrt{some ~random ~number}$

Haha obviously!! The answers are 11,29,42 or 58? I'm really bad at math so I'm pretty lost.

anonymous · Answer

area of a square with a side s:
Area = s * s
so, $$s=\sqrt{Area}$$

anonymous · Answer

I'm confused?

anonymous · Answer

because the wall is a square, the length and the width are he same.
$$length=\sqrt{Area}$$
then round it into nearest square (0.5 and above, round it up)
for example: 
13.7 = 14
13.2 = 13
