Textbook Problem

** Minimum fence** Two equal rectangular lots are to be enclosed by fencing the perimeter of a rectangular lot and then putting a fence across its middle. If each lot is to contain 1200 square feet, what is the minimum amount of fence needed to enclose the lots (include the fence across the middle)?

To determine

**To calculate:** The minimum amount of fence required to enclose the lots.

Explanation

**Given Information:**

Two rectangular lots of

**Formula used:**

To find the maximum value, calculate the relevant stationary value of an equation. Differentiate the function with respect to the independent variable and equate it to

If the second derivative of the provided function is less than zero, then substituting the value of the independent variable will give the maximum value of the equation.

The power rule is used for a function in which the expression can be written as every term raised to a power (be it fractional, positive or negative). For the function

**Calculation:**

As given, two rectangular lots of

Consider the perimeter of the rectangle is *P*

Thus, perimeter is

The two rectangles have a common side (breadth) which gives the total perimeter for fencing as

In the equation

Use the equation for area

Apply the equation
