will she need to buy?

Answer 1

Answer:

Step-by-step explanation

area of the 1 side walls= 0.2*2.5= 0.5m^2                          [20cm=0.2m]

area of 2 middle walls= 2*1*2.5= 5m^2

area of another side wall= 0.15*2.5=0.375m^2                   [15cm=0.15m]

area of another two middle walls=2*1.2*2.5=6

area of wall joining the two wings=0.25*2.5=0.625m^2

total area=12.5m^2

total area to be painted=25m^2

1 litre of paint= 10m^2

litres required=25/10

                       =2.5 litres
