Earboth made some valid points in this thread:

But if the following conditions are satisfied you can find some relations between the variables in question.

1. Conditions:
a) The sides of the rectangle are parallel to the coordinate axes.
b) The measures of the rectangle are (known) constant values: w, l.

2. Relations:
a)

If you want to get more relations then you must know the coordinates of the vertices of the rectangle.

You have not yet addressed these points.

In that rectangle I know width ,height and rectangle start X and start y. suppose , If I put a line in the center of the rectangle( parallel to the x axis)
then angle of that line is 0. and how we calculate x1, y1 and x2, y2 using formulas( directly we can tell x and y llike this --- x1 is startx , y1 is starty + height/2 and x2 is startx+ width and y2 is start y + height/2) I dont want that one. using formula how we calculate.
