Question

a museum director wants to hang a painting on the wall that is 90 feet. To the nearest foot, how tall does the wall need to be?

Answer 1

Answer: 10ft

Explanation:

I'm not quite sure I understand your question because you seem to have already stated the height of the wall but I found a similar one (see attached).

If the height of the picture is √90 feet. This means it is;

√90 = 9.5 ft

Rounded to the nearest foot is 10 feet.

To be able to hang the painting, the wall would have to be at least 10 ft in height.
