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»

Length of floor = 5 m and breadth of floor = 4 m

= 5 m x 4 m = 20 m²

Now, Side of square carpet = 3 m

Area of square carpet = side x side = 3 x 3 = 9 m²

Area of floor that is not carpeted = 20 m² – 9 m² = 11 m²
