A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric

Murrr4er [49]

Answer:

$A = 781250\,m^{2}$ , $x = 625\,m$ , $y = 1250\,m$

Step-by-step explanation:

The perimeter covered by the electric fence in meters is:

$2\cdot x + y = 2500$

The area of the rectangle is:

$A = x\cdot y$

$A = x \cdot (2500-2\cdot x)$

Let differentiate the previous equation and equates to zero:

$2500-4\cdot x = 0$

The critical point is:

$x = 625\,m$

By the Second Derivative Text, it is proved that critical point lead to a maximum:

$\frac{d^{2}A}{dx^{2}} = -4$

The other side of the rectangle is:

$y = 1250\,m$

The largest area than can be enclosed is:

$A = (625\,m)\cdot (1250\,m)$

$A = 781250\,m^{2}$

The dimensions of the triangle are:

$x = 625\,m$

$y = 1250\,m$

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.

sveta [45]

Answer:

<em>Answer: 512 inches</em>

Step-by-step explanation:

<u>Unit Conversion</u>

We need to recall two basic unit conversions for length:

1 inch = 2.54 cm

1 meter = 100 cm

We are given a length of 13 meters. Converting to centimeters:

13 * 100 = 1300 cm

Now convert to inches dividing by 2.54:

$1300 / 2.54 \approx 512$

Answer: 512 inches
