Solution :
Let us consider the squares be ![$[1, 16] \times [16, 32]$](https://tex.z-dn.net/?f=%24%5B1%2C%2016%5D%20%5Ctimes%20%5B16%2C%2032%5D%24)
If x ranges from the 0 to 16 and the y ranges from 16 to 32, we see that the boundary of the region
which goes from the
.
And so it is easier to find the area of region where
. This is the triangle with points
as its vertices.
The area if the triangle is = 
= 
Now the entire area is
= 256
Then, 
or 
Thus the answer is 
If he used 34 bottles for every batch just divide 214 bottles he used by 34 it takes for a batch
he made 6.3 batches
Whatever the person above said lol
11 (70-25=45, 45divided by 4=11
