Ex 1.1, 1 (iv) If B1 (0, 1.5) and B2 (0, 4) represent the ends of the bathroom door, is the bathroom door narrower or wider than the room door? The bathroom door lies on the y-axis (the left wall) between point B₁ at (0, 1.5) and point B₂ at (0, 4). To find its width, we subtract the smaller y-coordinate from the larger y-coordinate: Width of bathroom door = 4 – 1.5 = 2.5 units Thus, room door is 3.5 units wide, and the bathroom door is 2.5 feet wide. Therefore, the bathroom door is narrower than the room door.
