Adoor of length 2m and breadth 1m is fitted in a wall. the length of the wall is 4.5m and the breadth is 3.6m. find the cost of white washing the wall, if the rate of white washing the wall is ¥20 per m square

Cost of white washing = ¥284

Step-by-step explanation:

Given that:

Area of door = 2* 1 = 2m sq.

Area of wall = 4.5*3.6 = 16.2m sq.

As we have to white wash the wall so we will deduct the area of door from area of wall as follows:

Total area = Area of wall - Area of door

Total area = 16.2m sq - 2m sq

Total area = 14.2m sq.

As the cost of white washing is ¥20 per meter so total cost will be:

Cost of white washing = 14.2 * 20

Cost of white washing = ¥284
