Answer:
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
