Hey mate..
========
Given,
▪Height of the wooden door
= 2m 8cm
= 2.08m
▪Width of the wooden door = 1.2m
So, The total area of wooden door
= ( 2.08×1.2 ) m^2
=2.496m^2
The dimension of each pane is ••>
40cm by 20cm
i.e. 0.4m by 0.2m
Area of each glass pane
= (0.4×0.2) m^2
=0.08m^2
So, Area of 4 glass panes
=( 4×0.08 ) m^2
=0.32m^2
Therefore, area of wood
= (Total area of wooden door - area of 4 glass panes )
= (2.496 − 0.32) m^2
=2.176 m^2
Hope it helps !!

Answer:
Step-by-step explanation:
Length of wooden door =2m 8cm =2.08m. Width of wooden door= 1.2m.
Area=l×b=1.2×2.08=2.496m. .Area of each pane=40×20=80cm=0.8m.
Areaof 4 panes=0.8×4=0.32.
Area of wood =2.496-0.32= 2.176m
Ans =2.176m .
