First, we need to convert the area of the bedroom from square metres to square centimetres, so we multiply by 10,000:
25 square metres = 25,000 square centimetres
Now, we can find the size of each tile by dividing the total area by the number of tiles:
25,000 / 400 = 62.5
So each tile has an area of 62.5 square centimetres. Since a square has equal sides, we can find the length of one side by taking the square root of the area:
√62.5 = 7.91 (rounded to two decimal places)
Therefore, each tile is a square with sides of 7.91 centimetres.
