Question

Paul is painting a square wall with an area of 115 square feet. To the nearest foot, what is the length of the wall?

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

I'm confused?

Answer 5

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

Answer 6

ooooh ok i got it now! thanks!
