What you show is NOT the area enclosed by the graphs of these four functions but just the area between y1(x) and y2(x) in the the range 0<x<2.
I consider your way to plot the two orange vertical bars by defining two separate functions y3 and y4 to be very inefficient and uncomfortable. If you would decide to change your range x which you used for plotting, you would have to change these functions as well!!
From what I remember you asked very similar questions already in the past and where given working solutions there.
@ttokoro suggested using the bar plot feature, sometimes with the trick of plotting a graph in background color white to hide unwanted portions.
I provided a simple "Fill" function and LucMeekes offered an Express version of it.
In another thread I showed how to use a simple part of Prof. Birkeland's fantastic work to hatch fill irregular shapes.
All solutions given there in the past could be used with success for your 'new' problem as well, why didn't you gave it a try?

Here your new problem solved using the "Fill" function - no need to define extra functions y3 and y4
And here is a variant that takes your thread title verbatim
