A floor 10 meter long and 7 meter broad is to be paved with square tiles of side 0.5 meter . Find the number of tiles required .​

║⊕ANSWER⊕║

Length of the floor = 10m

Breadth of the floor = 7m

Area of the floor = length * breadth

                             = 10 * 7

                             = 70m²

Side of the square tile = 0.5m

Area of 1 square tile = side²

                                   = 0.5 * 0.5

                                   = 0.25m²

No.of tiles needed = Area of the floor / Area of 1 square tile

                                = 70 / 0.25

                                = 280

No.of tiles needed = 280 tiles
