Question

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

Answer 1

Using the units able the area of the farm land is

`\begin{gathered} (3)/(1.61)*(2.5)/(1.61) \\ =2.89 \end{gathered}`

Therefore the area of the farmland is 2.89 square mile

The number of truckload needed is:

`(2.89)/(0.8)=3.61`

Therefore the whole load of truckload is needed is 4

Total cost is

`\begin{gathered} 4*\$65.18 \\ =\$260.72 \end{gathered}`
