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.

Oh Ok! I also thought that the dog was inside the fence.:doh:

Avery very nice one. I like these things, please come up now with one like it if you have:cool::rose:

A fence of a house is 10m length (square)
If 10m is the length of the fence, the side of the square is only 2.5m. PI * 325 is ridiculously large. Or did you mean one side of the square is 10m?
Cheers, Vıkram.

Yes, very sorry if it wasn't clear enough.

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 ?

when it moves along the sides
Well, if it's constrained to moving along the sides, then it doesn't create a closed container, it only follows the edges. So the area is 0. Marc

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.:)

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
