You wish to temporarily mount a wire to serve as the antenna of your transmitter in your laboratory. It is necessary that this be straight and as long as possible. You recall that when you had the floor covered required exactly 140 square metres of carpet and that the long side of the room was 14 metres. You also know that the height of the room is 12 metres. You go to the store room to get the wire but find that it can only be supplied in lengths that are an integral multiple of 1 meter. What length of wire do you take back to the lab?
