Based on the grid layout, point D1 is located on the horizontal axis. We determine its position by counting 9 units from the origin along the North-South/East-West grid lines as described in the text. Since D1 lies exactly on the x-axis, its vertical position or y-coordinate is 0. Therefore, the exaRead more
Based on the grid layout, point D1 is located on the horizontal axis. We determine its position by counting 9 units from the origin along the North-South/East-West grid lines as described in the text. Since D1 lies exactly on the x-axis, its vertical position or y-coordinate is 0. Therefore, the exact coordinates of D1 are written as (9, 0), representing its horizontal and vertical distances respectively.

To compare the doors, we calculate their lengths. The room door width is 2.5 units (11.5 minus 9). The bathroom door lies on the y-axis, so we subtract its y-coordinates: 4 minus 1.5 equals 2.5 units. Since both calculations result in a distance of 2.5 units, the bathroom door is neither narrower noRead more

The width is calculated by subtracting the x-coordinates: 11.5 minus 9 equals 2.5 units. If we assume a standard scale where 1 unit equals 20 cm, the width is 50 cm. This is generally considered uncomfortable for a main room door. Specifically, a standard wheelchair requires a minimum width of about 80 to 90 cm to pass through easily. Therefore, a person in a wheelchair would not be able to enter easily.

In a coordinate system, the x-coordinate represents the perpendicular distance of a point from the y-axis (the left wall). For the door D1 R1, the x-coordinate of D1 is 9, meaning it is 9 units away from the left wall. The y-coordinate represents the distance from the x-axis. Since the door lies dirRead more
In a coordinate system, the x-coordinate represents the perpendicular distance of a point from the y-axis (the left wall). For the door D1 R1, the x-coordinate of D1 is 9, meaning it is 9 units away from the left wall. The y-coordinate represents the distance from the x-axis. Since the door lies directly on the x-axis, its y-coordinate is 0, meaning the door is zero units away from the x-axis.
