          Assuming that the dog cannot cross the fence. The dog will walk in an area like the following: dog.png (1.1 Kb) The area = 2 * area of rectangles + Area of the 1/6 the circle = 2 * 0.5 * 5 * sqrt(75) + 1/6 * pi * 100 Where did I go wrong?

          It is not like this, in fact it will move in a circles (Quarters) with radii 20, 15, and 5, then adding them and multiplying by 2 (Because it can go from the 2 sides) will give the solution, which is 325*PIm as Andy and Nish said.

                      Puzzle of the day. A fence of a house is 10m length (square) At point d a dog is tied, it can't go inside the house, when it moves along the sides it reaches the point x (max), Where the point x, and d are a midpoints of there sides. Q : What is the area that the dog can move in ?

                        d

                        That sentence was only to let them get the string length, as when it moves along the sides and reach the other side at the midpoint, so the length is 20m.:)

                          Awww, I took it to mean the fence was 10m in length, and took one side to be 2.5m. Otherwise, I think I would have beaten Nish Bot and Andy. :(

                              Here is one "like" yours A man placed 4 stepping stones one foot square in a row, in a section of his garden so that there were equal spaces on all four sides of each of the stones. What possible dimension, the section can have ? Keep rolling and, talking about stepping stones - "Mistakes are stepping stones to success.” oops... was that a hint ?

                                      That's why I hated math word problems in school. Because in my mind, "moving along the sides" means just that. It constrains to movement to the sides! Marc

                                          Awww, I took it to mean the fence was 10m in length, and took one side to be 2.5m. Otherwise, I think I would have beaten Nish Bot and Andy. :(

                                          Cheers, Vıkram.
