Question

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.

Answer 1

Step-by-step explanation:

Area of rectangle = length x breadth

= 5m x 3m

= 15m^2

area of square = side x side

= 3 x 3

= 9m^2

total area of the floor = 15 + 9 m^2

= 24m^2

Answer 2

Given:-

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

⠀

To find:-

• Area of the floor that is not carpeted.

⠀

Solution:-

According to the question,

→ Area of floor = l × b

→ 5 × 4

→ 20 m²

⠀

★ Side of a carpet = a = 3 m

⠀

→ Area of carpet = a × a

→ 3 × 3

→ 9 m²

⠀

Now,

→ Area of rectangular carpet - Area of square carpet

→ 20 - 9

→ 11 m²

⠀

Hence,

• the area of the floor that is not carpeted is 11 m².
