A floor is 5 m long and 4 m wide. A square carpet of sides 3 m is laid on the floor. Find the area of the floor that is not carpeted.

To find the area of the floor that is not carpeted, you first find the area of the entire floor and then subtract the area of the carpet.

Calculate the area of the entire floor: Area of the floor = Length × Width Area of the floor = 5 m × 4 m = 20 square meters.

Calculate the area of the carpet: Area of the carpet = Side × Side Area of the carpet = 3 m × 3 m = 9 square meters.

Find the area of the floor that is not carpeted by subtracting the area of the carpet from the area of the entire floor: Area not carpeted = Area of the floor - Area of the carpet Area not carpeted = 20 square meters - 9 square meters = 11 square meters.

So, the area of the floor that is not carpeted is 11 square meters.
