Answer 2

Room Tile Flooring Calculation

To calculate the size of the largest tile and the number of tiles needed to cover the floor of a room with dimensions 5m 25cm in length and 3m 25cm in width, we can follow these steps:

1. Calculate the Size of the Largest Tile: - To find the largest tile size, we need to determine the greatest common divisor (GCD) of the room's length and width in centimeters. - The GCD will be the largest tile size that can evenly fit into both the length and width of the room.

2. Determine the Number of Tiles Needed: - Once we have the largest tile size, we can calculate the number of tiles needed to cover the entire floor area of the room.

Calculation Results

1. Size of the Largest Tile: - The GCD of 525cm and 325cm is 25cm. - Therefore, the largest tile size that can evenly fit into both the length and width of the room is 25cm.

2. Number of Tiles Needed: - To find the number of tiles needed, we first convert the room dimensions to centimeters: - Length: 5m 25cm = 525cm - Width: 3m 25cm = 325cm - Then, we calculate the total floor area in square centimeters: - Total Area = Length x Width = 525cm x 325cm = 170625cm² - Finally, we divide the total area by the area of the largest tile to determine the number of tiles needed: - Number of Tiles = Total Area / (Largest Tile Size x Largest Tile Size) = 170625cm² / (25cm x 25cm) = 273 tiles

Therefore, to cover the floor of the room, you will need 273 tiles of size 25cm x 25cm.
