Areas of plane figures  
INTRODUCTION  
There are two pages for each geometrical figure. On the first page students have to do the equation of the area of this figure themselves. Therefore, the equation is not given. The next page is an exercise to find out its area. The dimensions of these figures are generated at random, which allows us to use them an indefinitely, resulting each time in a new exercise.
