We know that the formula for the area of a rectangle is:
We know that the area is 165. Now we need to solve for the dimensions.
Let the width of the rectangle be "
"
Then the length of the rectangle is
Substitute.
Multiply the terms.
Bring the 156 over.
We have to use the quadratic formula to solve this now. Let us restate it:
Now I'm going to fast forward this because all the rest is boring stuff and substitution. The answer is:
Since we cannot have a negative answer, we must cancel out the other answer, which I did not include.
Hope this helped! :)

Answer:
14.6328% , $5836.03
Step-by-step explanation:
Here we are going to use the formula
= 39000
r=?
= 11000
n=8
Hence
Hence r= 0.1463
In percentage form r = 14.63%
Now let us see calculate the value of car in 2003 that is after 12 years
we use the main formula again
= 39000
r=0.1463
= ?
n=12
Hence the car's value will be depreciated to $5840.34 (approx) by 2003.
