Which method describes the inventory process in which the last items to be
stocked are the first items sold?
A. MIFO
B. LIFO
C. FIFO

Hi There the correct answer to this is B. LIFO

Hope it helps!

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
