Question

A farmer has farmland that is rectangle 3km long and 2.5km wide. He wants to completely cover the farmland in dirt. He knows the area each truckload of dirt covers, but only in sq miles. Find the area of the farmland in square miles. Do not round intermediate computation and round your final answer two decimal places.

Answer 1

Given:

There are given that the length and width are:

`\begin{gathered} length:3km \\ wide:2.5km \end{gathered}`

Step-by-step 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,

`\begin{gathered} length:3km=(3)/(1.61)=1.86mi \\ width:2.5km:(2.5)/(1.61)=1.56mi \end{gathered}`

From the frmula:

`A=length* width`

Then,

Put all the values into the above formula:

So,

`\begin{gathered} A=length* wide \\ A=1.86mi*1.56mi \\ A=2.90mi^2 \end{gathered}`

Final answer:

Hence, the area is shown below:

`A=2.90mi^2`
