B, 13,600

Step-by-step explanation:

First we need to figure out the whole area

to do that we do

A = L x H

plug in your numbers

A = 200 x 80 and that gives up 16,000

now we need the area of the smaller rectangular

do the same equation just with the different dimensions

A = 60 x 40 and that gives us 2,400

now subtract the 2,400 from the 16,00 to get the total area of the shaded area

13,600

y=mx+b

step-by-step explanation:
