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 ) m2
=2.496m2
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) m2
=0.08m2
So, Area of 4 glass panes
=( 4×0.08 ) m2
=0.32m2
Therefore, area of wood
= (Total area of wooden door - area of 4 glass panes )
= (2.496 − 0.32) m2
=2.176 m2
