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

earnstyle [38]

The lateral area of the right octagonal prism is 672 square inches

<h3>How to determine the lateral area</h3>

The formula for lateral area of a right octagonal prism is expressed as;

Lateral area = 8ah

Where;

  • a is the side length = 7 Inches
  • h is the height of the prism = 12 Inches

Substitute the values into the formula

Lateral area = 8 × 7 × 12

Multiply through

Lateral area = 672 square inches
