Given:

There are given that the length and width are:

[tex]\begin{gathered} length:3km \\ wide:2.5km \end{gathered}[/tex]

Explanation:

(a):

To find the area of farmland, we need to use the area formula for rectangle:

So,

First find the given value from km to mies.

So,

[tex]\begin{gathered} length:3km=\frac{3}{1.61}=1.86mi \\ width:2.5km:\frac{2.5}{1.61}=1.56mi \end{gathered}[/tex]

From the frmula:

[tex]A=length\times width[/tex]

Then,

Put all the values into the above formula:

So,

[tex]\begin{gathered} A=length\times wide \\ A=1.86mi\times1.56mi \\ A=2.90mi^2 \end{gathered}[/tex]

Final answer:

Hence, the area is shown below:

[tex]A=2.90mi^2[/tex]
