A city has two main roads which cross each other at the centre of the city. These two roads are along the North–South (N–S) direction and East–West (E–W) direction. All the other streets of
the city run parallel to these roads and are 200 \(m\) apart. There are \(10\) streets in each direction.

(i) Using \(1 \ cm = 200 \ m\), represent a model of the city in your notebook. Also, Draw the roads/streets by single lines.
 

(ii) There are street intersections in the model. Each street intersection is formed by two streets — one running in the N–S direction and another in the E–W direction. Each street
intersection is referred to in the following manner: If the second street running in the N–S direction and \(5\)th street in the E–W direction meet at some crossing, then we call this street intersection \((2, 5)\). Using this convention, find:

(a) how many street intersections can be referred to as \((4, 3)\).

(b) how many street intersections can be referred to as \((3, 4)\).
