Question

Sibi wants to cover the floor of a room 5 m long and width 4 m by square tiles. If area of each square tiles is 2 1 m2, then find the number of tiles required to cover the floor of a room

Answer 1

Area of floor of a room = 5*4

                                     = 20 sq m

Area of square tile = 2 sq m

Number of tiles = 20/2

                          = 10 tiles
