A. the second should be centered at point j and pass through point A B. The third arc should be centered at point k and pass through point E
C. the second arc should be centered at point h and pass through point A
D. the third arc should be centered at point k and intersected the second arc

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
