To find the area of a square, you just square a side.

anonymous · Answer

So, to undo the square, we need to find the square root.

anonymous · Answer

$$\sqrt{480}=?$$

anonymous · Answer

Just round the answer to the nearest tenth, and then tell me what you got.

ok thanks

anonymous · Answer

Did you get the answer?

anonymous · Answer

anonymous · Answer

That's why I said round to the nearest tenth. It equals about 21.9

anonymous · Answer

So, round 21.9 to 22.

anonymous · Answer

yeah buts thats not an answer

anonymous · Answer

A square has 4 sides, and every side is equal. So, each side is 22 ft. long.

anonymous · Answer

Can you figure the perimeter from there?
