Orienting Yourself: The Use of Coordinates
Exercise Set 1.1
Fig. 1.3 shows Reiaan’s room with points OABC marking its corners. The x- and y-axes are marked in the figure. Point O is the origin.
Referring to Fig. 1.3, answer the following questions:
(i) If D1R1 represents the door to Reiaan’s room, how far is the door from the left wall (the y-axis) of the room? How far is the door from the x-axis?
(ii) What are the coordinates of D1?
(iii) If R1 is the point (11.5, 0), how wide is the door? Do you think this is a comfortable width for the room door? If a person in a wheelchair wants to enter the room, will he/she be able to do so easily?
(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?
Solutions:
(i) Given that D₁R₁ is the door. From figure D₁ ≈ (8, 0). Distance from y-axis (left wall) = 8 units. Distance from x-axis = 0 units. So, door is 8 units away from left wall and 0 units from x-axis.
(ii) From observation, D₁ = (8, 0).
(iii) Given R₁ = (11.5, 0) and D₁ = (8, 0). Door width = 11.5 − 8 = 3.5 units (ft). This is a comfortable width. A wheelchair can also pass easily (standard ~3 ft).
(iv) Given B₁ = (0, 1.5) and B₂ = (0, 4). Bathroom door width = 4 − 1.5 = 2.5 ft. Since room door = 3.5 ft and bathroom door = 2.5 ft, the bathroom door is narrower.
