Jenny made five loaves of banana bread that had 1/4 cup of oil in each loaf. after she was done baking, she had 5/8 cup of oil remaining. how much oil did she have before baking? cups

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

it should be a and d. lmk if i'm wrong xd
