Supriyabalaji, if there are many varied objects in your drawing, you can create a layer for the rectangles, then move them to that layer. To easily select all the rectangles and not other objects, create a filter for rectangles before window selecting. Once all rectangles are selected move them to the new layer, then turn off the other layers so other objects are not selected when you make the modifications to the rectangles. Next use the stretch command on each rectangle - best method once you learn how to use it. An alternative is to window select all the rectangles and explode them. Then use the offset command to shorten the length of the rectangles, and then trim the ends.

If I interpret your statement correctly, you want to crop the corners of a rectangle so that they are angled, and the angle has a rise/run of .08 & .36.
Here's how I would do it:
From one corner of the rectangle, draw a circle with Radius = .08mm
Then from the same corner point, draw a circle with Radius = .36mm
Whichever way you want the rise/run, draw a line from the intersection of one circle and a side of the rectangle to the intersection point of the other circle and the adjacent side of the rectangle.
Now you have a line at your rise/run.
The quick way to replicate it to the other 3 corners of the rectangle is to use the Mirror command.
Type "mi" or click the icon.
Pick the angled line as the object to mirror.
Press the Enter key (or the spacebar).
Pick the midpoint of one side of the rectangle and then pick the midpoint of the opposite side as the "mirror about".
Press the Enter key, then press it again because you do not want to delete the mirrored object.
Now you have 2 angled lines in opposite corners.
Repeat the above Mirror process, except this time pick both angled lines as mirror bjects and use the midpoints of the other 2 rectangle sides as the mirror about line.
Now you have angled lines in all 4 corners.
Type "tr" or click the Trim icon, pick the 4 angled lines as Trim lines, press Enter to get to the next step, then click on the ends of the rectangle side lines to trim them off.
Now you have a rectangle with angled corners.
