Answer:
2.25 square inches
Step-by-step explanation:
we know that
The scale is
That means
1 inch on a map represent 20 miles in the city
so
An area of on a map represent an area of
in the city
Applying proportion

Step-by-step explanation:
Take the first derivative
Set the derivative equal to 0.
or
For any number less than -1, the derivative function will have a Positve number thus a Positve slope for f(x).
For any number, between -1 and 1, the derivative slope will have a negative , thus a negative slope.
Since we are going to Positve to negative slope, we have a local max at x=-1
Plug in -1 for x into the original function
So the local max is 2 and occurs at x=-1,
For any number greater than 1, we have a Positve number for the derivative function we have a Positve slope.
Since we are going to decreasing to increasing, we have minimum at x=1,
Plug in 1 for x into original function
So the local min occurs at -2, at x=1
First, let's get the perimeter of the rectangle:
Then, let's get the area of the bigger one:
Then let's try using a rectangle with a smaller ratio:
Then:
If you used a square:
There you have it. A rectangle with a smaller area with the same perimeter.
What does it show? The smaller the difference you get from width and length, the larger the area is.
