Dog freedom?

There are four places the dog can be tethered, between which the area changes monotonically.

Therefore, their respective areas contain the extremal area values.

Spoiler for 'tieing

Sure. There are an infinite number of tie points.
Do you want a general equation?
Do you want the tie point for max or min?
Something other?

 

A simple range of values would suffice so that i know the potential roaming of my dog.

 

Bonanova provided the range in his first post. I came up with the same numbers too. Do you have a different answer?

I would argue that this question is a tricky question not a trick question. Too find the Range of yard for the dog you must consider ALL possibilities but you guys have only considered the house to be rectangular.

Yes I did make that assumption. Since it's late at night and my eyes are drooping, I'm sticking with the assumption. ;)

What would the area be if the dimensions referred to a different quadrilateral?  Like a parallelogram maybe.
