Answer:
4.0800*10^4
Step-by-step explanation:
4.9*10^4=49000
49000-8200=40800
since we can only have base numbers 1-9 in scientific notation, we need to move the decimal left 4 places:
4.0800*10^4

The transformation (x,y) --> (x,-y) is reflection over x axis. while the x coordinates in the image stay the same as the original, y coordinates change the sign.
Therefore coordinates of original image and final image after reflection
E - (0,3) --> E' (0,-3)
F - (2,2) --> F' (2,-2)
G - (1,1) --> G' (1,-1)
The diagram attached shows both the original image and image after reflection
40 x 50 = 2000, 4 x 5 = 20, 2000/20 = 100
