Street Plan : A city has two main roads which cross each other 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 these roads and are 200 m apart. There are about 5 streets in each direction. Using 1 cm = 200 m, draw a model of the city on your notebook. Represent roads/ streets by single lines. There are many cross-streets in your model. A particular cross-street is made by two streets, one running in the North - South direction and another in the East - West direction. Each cross street is referred to in the following manner : the 2^(nd) street running in the North -South direction and 5^(th) in the East - West direction meet at some crossing, then we will call this crossstreet (2, 5). Using this convention find : how many cross-streets can be referred to as (4, 3).

All the other streets of the city run parallel to these roads and are 200 m apart. There are about 5 streets in each direction. Using 1cm = 200 m, draw a model of the city on your notebook. Represent the roads/streets by single lines. There are many cross– streets in your model. A particular cross–street is made by two streets, one running in the North – South direction and another in the East – West direction. Each cross street is referred to in the following maimer : If the 2nd street running in the North – South direction and 5th in the East – West direction meet at some crossing, then we will call this cross–street (2. 5). Using this convention, find: (i) how many cross – streets can be referred to as (4, 3). (ii) how many cross – streets can be referred to as (3, 4).
