Your words are so poorly chosen that it is hard to figure out what you are talking about. You need an editor to correct your English before you can call this a math problem.
~ What is a circled pasture?
~ A circle does not have a corner.
~ "Somewhere on the corner" is meaningless. It's either on the corner or it's not.
~ "Which" is spelled with two h. "Witch" is spelled with one h and a t and it is a female person.
~ The pasture has to be square to make sense in the problem, but you don't ever say "square".

If R = 10 m is the radius of the circular meadow, the rope, which is somehow attached to the perimeter of the meadow, has a length of
