Which pair of lines are perpendicular?
A) 8x - 4y = 24; Y=-2x+7
B) = 3v = 15; y = 3x+4
C) 21 - 5y = 5; 5x - 2=4
D) x + y = 10; x-y=3
E) 5x-y=1;y=1/5x+9

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
