Answer:
2xy
The expression for the area of a square with side [tex]x[/tex] is [tex]x*x=x^{2}[/tex]
If you cut the square in half, you will have two rectangles with side [tex]x[/tex] and height [tex]y[/tex] so each area will be [tex]x*y=area[/tex]
The total is the adding of the individual. You have two areas the expression will be [tex]Total Area= (x*y) + (x*y)= 2xy[/tex]
