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

${\huge{\underline{\underline{\sf{\blue{answer :-}}}}}}$

Area of floor that is not carpeted is 11 m².

Step-by-step explanation:

To find:-

Area of floor that is not carpeted.

Solution:-

Given that,

A floor is 5 m long and 4 m wide. A square carpet of sides 3 m is laid on the floor.

Side of carpet = 3 m.

Shape of carpet is square.

Area of square = Side × Side

⟶ 3 × 3

⟶ 9

Area of carpet is 9 m².

Length (given long) of floor is 5 m.

Breadth (given wide) of floor is 4 m

Length and breadth is given. So, the shape of floor is rectangular.

Area of rectangle = length × breadth

⟶ 5 × 4

⟶ 20

Area of floor is 20 m².

Area of floor that is not carpeted = Area of floor - Area of carpet.

⟶ 20 - 9

⟶ 11

Therefore,

Area of floor that is not carpeted is 11 m².
