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

hm let me think hm think think hm think yes

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
