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 200m apart. There are 5 streets in each direction. Using 1cm= 200m, draw a model of the city. Represent the roads/ streets by single lines.
