This is an actual question from the boys homework. Can someone please explain to me how this teaches math.
Mr. Badilla is building a rectangular fence around his back yard. He needs to buy enough fencing material to cover two lengths and one width. Mr. Badilla knows that his stride is about one half meter long. Describe a way that Mr. Badilla could estimate the amount of fencing material he will need.
Am I just stupid, or is this a fucking un-answerable question?
