What are your thoughts regarding this problem? Have you made any attempts to solve it yet?

anonymous · Answer

Yes, I'm thinking it is a since she has 120 meters of rope and 12 * 10 = 120?

Is that right?

That might be your first impulse, however the 120 meters of rope can't represent area. Using rope, you can rope off an area but you can't say that the length of the rope is the area.
