  1. Answer:

    Out of the four walls to be painted,  

    2 wall have the dimensions (8×4) cm

    and other 2 walls have the dimensions (6×4) cm

    So, total wall area to be painted =2(8×4)+2(6×4)

    =2(32)+2(24)

    =64+48

    =112 cm  

    2

     

    Rate of cost of painting =0.045 /cm  

    2

     

    So, total cost =0.045×112

    =Rs.5.04
