The area of the lane is 50 in² and its perimeter is 30 in.
<h3>
What is an area</h3>
Area is the amount of space occupied by a two dimensional object or figure. For a rectangle:
Area = length * width
Let the length of the lane be 10 in and the width be 5 in, hence:
Area = 10 * 5 = 50 in²
Perimeter = 2(length + width) = 2(10 + 5) = 30 in
The area of the lane is 50 in² and its perimeter is 30 in.

The answer is N(-3,3) the formula of reflecting across the x-axis is (x,-y)
The answer for the blank is 0.003
This is the slope value, which is the number in front of the x in the least squares regression line. Each time x increases by 1, y increases by 0.003
This is the predicted y value of course.
Let
x---------> the length side of the rectangular area
y---------> the width side of the rectangular area
we know that
the area of the rectangle is equal to

-----> equation 
The perimeter of the rectangle is equal to

but remember that the fourth side of the rectangle will be formed by a portion of the barn wall
so
-----> equation 
<em>To minimize the cost we must minimize the perimeter</em>
Substitute the equation
in the equation 
![P=x+2*[\frac{200}{x} ]](https://tex.z-dn.net/?f=%20P%3Dx%2B2%2A%5B%5Cfrac%7B200%7D%7Bx%7D%20%20%5D%20)
Using a graph tool
see the attached figure
The minimum of the graph is the point 
that means for 
the perimeter is a minimum and equal to
