Answer:
If the problem is,

By finding it,
Take a 5 box grid in which each box represents 1 unit,
Then take 1 box of this grid,
Repeat this step,
Finally, Add them,
We get,
A grid having 10 boxes with 2 taken boxes,
Thus, 
When we do these steps for three grids we will get
,
That is, by multiplying the result of
by 3 we will obtain 

The equations would cancel each other out, so the answer would be infinitely many.
I believe the answer is 3/5 pi cm (I couldn't figure out how to add the pi symbol).
1/5 would be .20, because 20/100 is 1/5. 4 out of 20 would be .20 as well. To compare them, they have the same value.
