Question

A wooden door 2m 5cm high and 1.1m wide has 4 glass panes fitted in between. Each pane is 40cm long and 25cm wide. What is the area of the wood?

Answer 1

Answer:

185.5m^2

Step-by-step explanation:

length of the door=>2m5cm=205cm

breadth of the door=>1.1m=110cm

Area of the door=l*b = 205cm*110cm

=22550cm^2

given,

4panes each of length=40cm

breadth=25cm

Area of each pane =l*b=40*25cm

=1000cm^2

Area of 4 panes=4*1000cm^2

=4000cm^2

Area of wood = Ar. of door - Ar. of 4 panes.

=22550cm^2 - 4000cm^2

=18550cm^2

=185.5cm^2 Answer...
