NCERT Class 9 Maths Chapter 3 Coordinate Geometry Solutions Exercise 3.1 Q.1. How will you describe the position of a table lamp on your study table to another person? Ans: Consider the lamp placed on the table. Take the space taken by the lamp as a point and draw perpendiculars on length AB and breadth BC of the table. Now measure the distance. Let the length of perpendicular be 20 cm and 30 cm from length AB and breadth BC respectively. So, the position of the lamp from (AB, BC) edges will be (20, 30). Q.2. (Street Plan): A city has two main roads meeting at the centre of the city. These two roads are along the North-South direction and East-West direction. All other streets of the city run parallel to main roads and are 200 m apart. There are about 5 streets in each direction. Using 1 cm=200 m, draw the model of the city on your notebook. Represent roads/streets by single lines. There are many cross streets in our modal. A particular cross-street is made by two streets, one running ...
