Answer 1

Answer:

Step-by-step explanation:

We know that the area of a square tile is 1/ meter-square.

So, we have to find required number of tiles to cover the whole floor. To solve this problem, we have to find total area of the floor first.

So, total area of the floor is 5 * 4 meter-square

                                            = 20 meter-square.

So, total number of tiles = are of the floor / area of one tile

                                        =

                                        = 40

Answer: required number of tiles = 40.
