Math Challenges!

At the beginning of each month a Math challenge will come out.

To solve the challenge correctly, you have to:

  • Write the solution with an explanation on a paper with your name and group and left it in the mailbox situated in the hall, before the first day of the following month.
  • Write the reasoned solution in this website (at the bottom of the article).

There will be 3 categories: 

  • Pupils (ESO, Batxillerat and Professional Studies).
  • Teachers and PAS.
  • Web visitors.


We have a triangle with sides 15, 20 and 25 cm. We cut the vertices to 5 cm so that an
irregular hexagon is formed. Calculate the area of this hexagon.
