You are given a rectangle which is parallel to the coordinate axis. The lower left coordinate is **(x,y)** and the length of two sides are **r** and **c** ( described in figure ). You can easily construct the rectangle by connecting these **4** points **{ (x,y) , (x+c,y) , (x+c,y+r) , (x,y+r) }** in anti-clockwise order.
**Fig : A line drawn form (px,py) dividing the rectangle into two equal parts (according to area). Note that, the figure may not be mathematically accurate. It is used just for understanding purposes.**
