Let's divide the shaded region into two areas:
area 1: x = 0 ---> x = 2
ares 2: x = 2 ---> x = 4
In area 1, we need to find the area under g(x) = x and in area 2, we need to find the area between g(x) = x and f(x) = (x - 2)^2. Now let's set up the integrals needed to find the areas.
Area 1:

Area 2:





Therefore, the area of the shaded portion of the graph is
A = A1 + A2 = 5.34
I would say option 3 hopefully im right!!
A millimeter is a one dimensional measurement whereas a liter is a three-dimensional measurement. There is no equivalence between the two.
If you meant milliliter, that is also equivalent to a cm^3, of which there are one thousand in a liter.
1000ml=L or 1000cm^3=L
