This Area
Pronoun and の adjective
このへん
この辺は、人が少ないのでしずかです。
There aren’t many people around here, so it’s quiet.
この辺に、スタバはありますか？
Is there Starbucks around here?
この辺では、言葉に気をつけた方がいいぜ。町のこちら側に住んでいるやつらは、口笛を吹いただけでも顔に唾をぶっかけてきやがるからな。
You have to be careful about what you say around here. People on this side of town will spit in your face just for whistling.
この means "this" so この辺 just means this area.
The reading for the kanji portion is just what you've already learned with the kanji 辺 so this shouldn't be a difficult one to read for you.
