Now the overlap should 2020 units for the thickness and 55 units additional overlap on each side i.e a total of 2525 units on each side.

as such while length should be 200+2xx25=200+50=250200+2×25=200+50=250 units

and width should be 160+2xx25=160+50=210160+2×25=160+50=210 units

i.e. dimensions of the sheet should be 250xx210250×210 units.
