(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 the other streets of
the city run parallel to these roads and are 200 m apart. There are 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 manner: 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
(i) How many cross-streets can be referred to as (4, 3).
(ii) How many cross-streets can be referred to as (3, 4).
The street plan is shown by the following figure.
(i) There is only one cross-street which could be referred to as (4, 3).
(ii) There is only one cross-street which could be referred to as (3, 4).
