Answer» Correct Answer - Option 3 : 11 m² Given: Length of the floor = 5 m Breadth of the floor = 4 m Side of square carpet = 3 m Formula used: Area of the rectangle = (l × b) Where, l → Lenght b → Breadth Area of square = (side)² Calculations: Area of the rectangle = (l × b) ⇒ (5 × 4) = 20 m² Area of square carpet = (side)2 square unit ⇒ (3)² = 9 m² Uncarpeted area = (20 – 9) = 11 m² ∴ The area of the floor that is not carpeted is 11 m²

Answer» Correct Answer - Option 3 : 11 m²

Given:

Length of the floor = 5 m

Breadth of the floor = 4 m

Side of square carpet = 3 m

Formula used:

Area of the rectangle = (l × b)

Where,

l → Lenght

b → Breadth

Area of square = (side)²

Calculations:

Area of the rectangle = (l × b)

⇒ (5 × 4) = 20 m²

Area of square carpet = (side)2 square unit

⇒ (3)² = 9 m²

Uncarpeted area = (20 – 9) = 11 m²

∴ The area of the floor that is not carpeted is 11 m²
