You can put this solution on YOUR website!
1 meter = 100 Cms.
1 Sq.meter = 100 X 100 = 10000 Sq.Cms.
32 Sq.meters = 320000 Sq.Cms.
Area of 1 tile = 50 x 50 = 2500 Sq.Cms.
To cover the entire floor = 320000%2F2500+=+800
So, to cover the entire floor, one needs 800 tiles.
First convert the area of the floor into centimeters as the tiles are in the measure of centimeters. Then find the area of a tile. Now both are in centimeters. You can easily find out the no. of tiles by dividing the area of the floor by area of the tile. There you get the answer. I hope you understood.
