Answer 2

Answer:

Area of the floor which is not carpet = 31m^2

Step-by-step explanation:

Given:-

• Length of room = 8m
• Breadth of room= 5m
• Side of carpet= 3m

To Find:-

• Area of the floor which is not carpet

First we find the area of room

→ Length × Breadth

→8×5 = 40m^2

Then we find the area of carpet

→ Side × Side

→ 3×3 = 9m^2

So,

→ Area of the floor which is not carpet= Area of room - Area of carpet laid on floor

→ = 40 – 9 = 31m^2
