The side of a square ceramic tile is 10 cm. How many of these tiles are required to cover a bathroom floor that is 2 m 50 cm long and 2 m wide?

To solve this problem, recall the formula for the area of a rectangle. The area of a rectangle is equal to the product of its length and width. S = a * b, where a is the length and b is the width. Knowing that the floor length is 2 m 8 cm, and the width is 2 meters, we calculate the floor area. Let’s convert meters to centimeters. 1 meter = 100 centimeters. 2 m 8 cm = 2 * 100 + 8 = 208 cm.2 m = 2 * 100 = 200 cm.
S = 200 * 208 = 41,600 cm ^ 2.
Recall that the area of a square is equal to the square of its side. We calculate the area of the tile, knowing that the side is 10 cm.
S = 10 * 10 = 100 cm ^ 2.
Let’s calculate how many tiles you need.
41600/100 = 416 tiles.
Answer: 416 tiles.
