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

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
