The problem goes like this :

There is a square of 1 meters per 1 meters. On each side of the square, we build a new square which is side is the third of the side of the previous square. On each side on the new square, we build a new square of the third of the side of the previous. and it continue until the infinity. We want to know what is the surface of all those squares togother.

I hope you understand what I mean.

Somebody I an idea how to solves this ?
