A room is 13m long and 9m broad. A square
carpet of side 8m is laid down on its floor .
Find the area of the floor which is not covered
by the carpet.
What is (13)(9) - 8^2 ?
To find the area of the floor that is not covered by the carpet, we first need to find the area of the floor and then subtract the area of the carpet.
The given dimensions of the room are:
Length = 13m
Breadth = 9m
To find the area of the floor, we multiply the length and breadth of the room:
Area of the floor = Length × Breadth
Area of the floor = 13m × 9m
Area of the floor = 117m²
Now, let's find the area of the carpet. The given side of the square carpet is 8m:
Area of the carpet = Side × Side
Area of the carpet = 8m × 8m
Area of the carpet = 64m²
To find the area of the floor not covered by the carpet, we subtract the area of the carpet from the area of the floor:
Area not covered by the carpet = Area of the floor - Area of the carpet
Area not covered by the carpet = 117m² - 64m²
Area not covered by the carpet = 53m²
Therefore, the area of the floor that is not covered by the carpet is 53m².
