Answer:
7 milligrams
Step-by-step explanation:
First we have to find length of 1 side of the square. We can use formula for area of the square. A=a*a ==>

where a is length of the side.
From this formula we can find

a=

Now we just have to multiply it by 4, because there are 4 sides.
81*4=324 - its the answer
31 is g = -19
32 is x = -9
34 is w = -11
31:
g-(-7) = -12
g+7 = -12
g = -19
32:
-5x = 45 divide by -5
x = -9
33 looks like it has a print error so I can’t figure that out, I don’t know where the |-2| is supposed to be
34:
(w-1)/4 = -3 multiply by 4
w - 1 = -12
w = -11
