Question

Exactly 640 acres are in one square mile. how many square meters are in 2.2 acres

Answer 1

640 acres = 1 square mile

So we can say 1 acres =
`(1)/(640)` square mile

So in 2.2 acres =
`2.2 * (1)/(640)` square mile

= 0.0034375 square mile

In general one mile = 1609.344 meters

So one square mile = 1609.344 * 1609.344 square meter

= 2589988 square meter

So 0.0034375 square mile = 0.0034375 * 2589988
= 8903.08375 square meter.
