Right answer is (a) Height = (width + 1.2) metres
The best explanation: The height and the width of a door are related in a way such that the height of the door is 1.2 metres more than the width of the door. For example, if the width of a door is 0.8 metres, then its height will be (0.8 + 1.2) m i.e. 2 metres.
