Question

a floor is 15cm long and 10cm wide . a square carpet of side 9cm is laid on floor . find the area of the floor which is not carpeted​

Answer 1

Step-by-step explanation:

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

Area of floor = length x breadth

= 5 m x 4 m = 20 m.sq

Now, Side of square carpet = 3 m

Area of square carpet = side x side = 3 x 3 = 9 m.sq

Area of floor that is not carpeted = 20 m – 9 m = 11 m.sq
