breadth is 3.6m. Find the cost of whitewashing the wall if the rate of whitewashing the wall

Answer 1

Area of wall = l× b.

= 4.5 *3.6 = 16.2 m^2

Area of door = l*b

= 1*0.5 = 0.5 m^2

To whitewash total walk to be whitewashed =

16.2-0.5 = 15.7 m^ 2

Total cost of 1 m^2 = 20

Total cost 20*15.7 = 314 rupees
