Answer 2

Answer:132m

Step-by-step explanation:

11m=length

9m=width

2m=distance from the centre to the wall

first multiply 11 by 9 which gives us 99m for the carpet. Now we want to find  the area of the room which is when we have to add 11m by 2m which gives us 12m which is our length for the room and now for our width we add 9m by 2m which gives us 11m of the width. Finally we multiply 12m by 11m which gives us 132m which is our area for the room
