Answer:
The average rate of change is equal to
Step-by-step explanation:
we have
-----> this is a linear direct variation
we know that
The rate of change of a linear variation is a constant
The rate of change of a linear variation is equal to the slope of the line
In this problem the slope of the line is equal to
therefore
The average rate of change is equal to
<u>Verify</u>
the average rate of change is equal to
In this problem we have
Substitute
Set the width to be x. Thus, the length is 4x.
The perimeter is 2(x+4x)=100, so x=10.
Plugging in x=10, you get that 4x=40.
So, the area of the rectangle is 400 .
Because there are 100 centimeters in a meter and you are asking for area, you must multiply by to get 4000000
