Cathy lives in a state where speeders are fined $12 for each mile per hour over the speed limit. Cathy was given a ticket for $84 for speeding on a road where the speed limit is 45 miles per hour. How fast was Cathy driving?

52 miles per hour

Step-by-step explanation:

From the above question speeders are fined $12 for each mile per hour.

Cathy was fined $84 on a road where the speed limit is 45 miles per hour.

If the fine charges per mile per hour is $12. The to find the no of miles per hour Cathy was over with is

$84/$12 = 7

Therefore 45 miles per hour plus 7 miles per hour is 52 miles per hour.

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

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
