Wavelength is a measure of distance not area. It is the distance traveled by a signal from a Zero state to a Plus One state back through Zero to Minus One and returning to Zero.

None! They both mean the same thing. For example, if your floor measures 3 meters long and 2 meters wide you would need 6 square meters of carpet. Alternatively you could say "My floor measures 6 meters squared." Five meters squared. This refers to a linear measure, five meters. It also tells what function to apply to the measure-- make a square with it. If I make a square with a five meter chain, I will end up with 25 square meters. Five square meters. This will be equivalent to five of the 25 squares that the above area contains. Quite different. If you have a floor measuring 3 meters by 2 meters and you ask the carpet guy for carpeting to cover 6 meters squared, you will get an unpleasant surprise.
Speed = (wavelength) times (frequency) = (wavelength) divided by (period) = 30/5 = 6 meters per second
A wavelength that measures 10^2 would be 100 meters long.

The length of the rope would be half the wavelength of the standing wave, so in this case, the rope would be 5 meters long. This is because the fundamental frequency of the standing wave has one full wavelength, which corresponds to half the length of the rope.
Speed = (wavelength) times (frequency) = (wavelength) divided by (period) = 30/5 = 6 meters per second
