The perimeter of a rectangle is the sum of twice the width and twice the length
The function that gives the cost of fencing is given from the graph by the following function;
Please find attached the required diagram
The given parameter are;
The area of the square rectangle = 250 m²
The length of the side of the pen wall parallel to the coop = x
The cost of fencing per foot, c = $10
The function for the cost in dollars of fencing, C(x) = 10x + 5000
Solution:
Let <em>y</em> represent the length of the other side, we have;
x × y = 250
Perimeter, P = x + 2·y
The length of the fencing required, P = x + 2·y
The total cost of the fencing, C(x) = c × P
Therefore;
