To Find:

Cost of washing walls and ceiling ?

Step-by-step explanation:

• We have Length of room=6m

• breadth of room=5m

• height of room=2m

• Area of room  four walls is given by the formula

        [tex]\textrm{AREA Of four walls}= 2 height(l+b)\\ Area=2\times 2 (6+5)\\ Area= 44m^2[/tex]

• Area of ceiling is given by

        [tex]Area=l\times b\\ =30m^2[/tex]

       Toral area =44+30=74

• We have cost of washing per $m^2$ =6.5

Cost of washing 74$m^2$ =6.5 74=Rs.4810

Hence, total cost is 4810.
