Answer 2

A total of 8000 k.g. manure is required and the cost of fencing the farm is ₹ 6400.

Step-by-step explanation:

• Here given that the area of the square farm is 1600 sq m and also it has a boundary of 160 m.

• firstly, we need to compute the amount of manure required.

• Given that 5 kg of manure is required per sq. m.

So,

    $Total\hspace{0.2 cm} manure\hspace{0.2 cm} required = manure\hspace{0.2 cm} required\hspace{0.2 cm} per\hspace{0.2 cm} sq.\hspace{0.2 cm} m * area\hspace{0.2 cm} of\hspace{0.2 cm} farm$

                                            $= 5\hspace{0.1 cm} k.g \times 1600$

                                            $= 8000 \hspace{0.1 cm} k.g$

• Now we need to calculate the cost of fencing the farm.

• Given that it costs ₹ 40 per m.

So,

    $Total\hspace{0.1 cm} cost\hspace{0.1 cm} of\hspace{0.1 cm} fencing=per\hspace{0.2 cm} unit \hspace{0.2 cm} cost \times the\hspace{0.2 cm} boundary \hspace{0.2 cm} of\hspace{0.2 cm} farm$

                                        $=Rs \hspace{0.2 cm} 40 \times 160$

                                        $= Rs\hspace{0.1 cm}6400$

Hence, a total of 8000 k.g. manure is required and the cost of fencing the farm is ₹ 6400.
