52.8
84.48

How many miles are in 19.08 kilometers?
11.925
17.48
20.68
30.528

Step-by-step explanation ithink your are correct because that there 19.08+18.3=11.925

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
