the back of the screen of my macbook air m2 getting hot

I'm living in a city which reaches temperatures of 35 º to 40º degrees celsius. and the back of my laptop's screen gets too warm when the display brightness reaches 50% or more, is it normal or not ?

although i have used many macbooks in the same condition but I have never experienced the same thing ( 13' mbp 2015, 13' mbp 2017, 13' mbp 2011 ) I don't know if it's a common problem among new macbook m2 airs, or the problem is in my computer.
