Area Calculation MCQ6: The perimeter of a floor of a room is 18m .what is the area of four walls of the room ,if its height is 3m.

a)  21 Sq.m           b) 42 Sq.m            c) 54 Sq.m              d) 108 Sq.m

Solution:

We suppose that the room is rectangle shape.

drawit diagram 16

Here,

L= Length of the room

B= Breadth of the room

We know perimeter of a rectangle is ;

\[ Perimeter = 2(L+B) \]

drawit diagram 17

But

Perimeter = 18 m

So,

\[ 18=2(L+B) \]

This the total length of the boundary walls as well. And height of the all boundary wall is 3 m.

So if we multiply total length with total height the area of the surface of the boundary walls is calculated.

\[ Area = Height \times Length Of Boundary Wall= 3\times 2(L+B)=3\times18=54 m^2 \]

So the area of walls is 54 meter square
