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

Area of floor = l × b

= 5 × 4

= 20 m²

Area of square carpet = 3 × 3

= 9 m²

Area of floor that is not carpeted = 20 – 9

= 11 m²

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