Answer: 52.5cm²
Step-by-step explanation:
Firs, you have to split this composite shape into two separate shapes; a rectangle and triangle.
To work out the area of the rectangle you would have to do 8x5=40.
To work out the area you would have to find out the height of it first. So, to do this you would have to do 1+2=3 then do 8-3=5. Now we know the height is 5.
Then you have to use the formula base times height divided by 2 (b×h/2). So 5×5=25 then 25÷2=12.5
To then find the total area of this composite shape you would have to add the two areas together. So 40+12.5=52.5cm²

Let the number of times she turns the pedal in one mile be x.
Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then
Therefore, she turns the pedal 500 times in one mile.
The value of this car when it is 9 years old is equal to $16,757.00.
<h3>How to calculate the value?</h3>
In order to determine the value of this car when it is 9 years old, we would use an exponential function which also relates to compound interest as follows:
A = P(1 - r)^t
Substituting the given parameters into the formula, we have;
A = 32,200(1 - 0.07)^9
A = 32,200(0.93)^9
A = 32,200 × 0.5204
A = $16,757.00.
