Anyone know anything about maths? Here's a puzzle for you:
A floor is decorated with a tiled mosaic. The whole mosaic is a regular pentagon. It is made from 4 types of tiles. The length of the side of the whole mosaic is just over 6 times the length of the side of one pentagon tile.
How many of each type of tile make up the mosaic?
Question: How is this worked out mathematically? Is it a formula of some sort or just a case of playing around with pentagon shaped tiles?
