Question

Area of four walls of a room = perimeter of floor X height of walls. TRUE OR FALSE

Answer 1

Answer:

true

Step-by-step explanation:

area of four wall = 2(l + b)x h

Answer 2

It is true that, Area of four walls of a room = perimeter of floor × height of walls.

To properly understand this answer, we have to discuss about the area of four walls of a room.

3 dimensions of a room :

1. Length
2. Breadth
3. Height

And, a room has :

• A roof and a floor.
• Four walls.

The above mentioned planes of a room can be calculated by using the previously mentioned 3 dimensions of the room.

Now, area of roof or floor of a room

= Length × Breadth

And, area of four walls of a room :

= Floor perimeter × Height

= [2×(Length + Breadth)] × Height

So, area of four walls of a room can be also calculated by the three dimensions of a room (i.e. length, breadth and height). And, this area of four walls is often calculated while calculating the total cost for painting,cementing or whitewashing four walls of a room.

Hence, it is true that, Area of four walls of a room = perimeter of floor × height of walls.
