Hexagonal tiles of side 20cm are used to tile a room which measures 6.25m by 4.85m. Assuming we complete the edges by cutting up tiles, how many tiles are needed?
The area of a regular hexagon of side x is approximately 2.598*x^2. As the side of the hexagonal tile is 20 cm, its surface area is approximately 1039.2 cm^2
The area of the room is 625*485 = 303125 cm^2
To cover the area of the room using the tiles approximately 292 tiles are required.
