Question
Two stakes are nailed into the ground, 8 meters apart. The ends of a 10-meter-long inextensible rope are tied to these stakes. A robot is tied to the rope such that the robot may move along the rope but remains attached to it, and may move in any direction not restricted by the rope. Find the area (in square meters) of the region in which the robot may travel.
