Did I understand correctly, the first number is:

?
in other words, this would be:

and if you drink half of it, then we divide this number by 2:

because 30/2=15
so you would have

still more than a daily dose!
Answer:
12

Answer:
40
Step-by-step explanation:
SO im guessing if its the full graph one box counts 1.
So the top side counts 8
The left one is 15
The perimeter means adding all the sides together.
We already have 2. But finding the hypotenuse would not be easy from graph so we will use Pythagorean theorem.
a^2+b^2=c^2
8^2+15^2 = c^2
64+225 = c^2
289 = c^2
c = 17
so the perimeter is 8+15+17 = 40
