Question

A room is 14 m
long and 12m wide. A square carpet of side tom is to be laid on its door. Find the area of the floor which is not carpeted.


​

Answer 1

Given:

Length of the room =14 m

Breadth of the room =12 m

Area of the room = (length × times breadth)

  =(14 × 12 )

   =168 m²

Area of the square carpet =(side)²  

   =(12)²

  =144 m²

Area of the floor which is not carpeted = (Area of the room)-(Area of the carpet)

 =168-144

  =24 m²

Hence, area of the room which is not carpeted is 24 m²

Answer 2

Given that:-

Length of the room = 14m

Breadth of the room = 12m

To find the area of the floor,

As we know that, the formula of area is

Area  = (length × breadth)

$=>(14*12)$

$=>168m^{2}$

The square carpet is $2$m,

We have the formula,

Area of square = $(side)^{2}$

$=>(2)^{2}$

$=>4m^{2}$

Area of the floor which is not carpeted = (Area of the room)-(Area of the carpet)

$=>(168-4)m$

$=>164m^{2}$

Hence, area of the room which is not carpeted is $164m ^{2}$
