Urban area.

I tried to find the urban extent of vizag excluding it's hills. Bheemli is not included in vizag-2, which covers an area of 37km² encompassing the areas of Yendada, Rushikonda and Madhurwada. I included the areas of Angampudi and Pendurthi in Vizag-1 although they're somewhat quite far from the 'core' city of Vizag. Vizag-1 encompasses an area of about 237km². Combining these, the total urban extent of Vizag is approximately 280 km². Allowing for a margin of error (30-40 km²), the range would be between 250 and 320 km².
