1.	A room is 20m long and 10m wide. a 10m square carpet is laid on the floor.[a] find the area not carpeted
Answer» Answer :- The area not carpeted is 100m². Step-by-step explanation: To Find :- Find the area not carpeted Solution: Given that, A room is 20m LONG and 10m wide, Length of the room = 20m Breadth of the room = 10m Therefore, Area of the room: => Length × Breadth => 20m × 10m => ( 20 × 10 ) m² => 200m² Also given, A 10m square carpet is LAID on the floor, Side of the square carpet = 10m Therefore, Area of square carpet: => ( side )² => ( 10m )² => 100m² Now, According the question, The area not carpeted: => Area of the room - Area of the square carpet => 200m² - 100 m² => ( 200 - 100 ) m² => 100m² Hence, The area not carpeted is 100m².

A room is 20m long and 10m wide. a 10m square carpet is laid on the floor.[a] find the area not carpeted

Answer»

To Find :-

Solution:

Given that,

A room is 20m LONG and 10m wide,

Therefore,

Area of the room:

=> Length × Breadth

=> 20m × 10m

=> ( 20 × 10 ) m²

=> 200m²

Also given,

A 10m square carpet is LAID on the floor,

Therefore,

Area of square carpet:

=> ( side )²

=> ( 10m )²

=> 100m²

Now, According the question,

The area not carpeted:

=> Area of the room - Area of the square carpet

=> 200m² - 100 m²

=> ( 200 - 100 ) m²

=> 100m²

Hence,
