Linda was pulled over by a policeman for driving 80 miles per hour. One mile
is about 1.61 kilometers. About how
many kilometers per hour was Linda
driving when she got pulled over by the
policeman?

128.74

Step-by-step explanation:

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

(23*2)-12=x     x=34
