# If one square mile is 640 acres, how many square meters are there in 1 acre?

Mar 20, 2016

(Approximately) $4046.83 \text{sq.m."/"acre}$

#### Explanation:

$1$ mile $= 1 , 609.34$ meters

(from here on I used a calculator)

$1 \text{ sq. mile "= (1,609.34)^2 = 2,589,975.24 " sq. meters}$

$\left(1 \text{ sq. mile")/(640 " acres}\right)$

$\textcolor{w h i t e}{\text{XXX")=(2,589,975.24 " sq. meters")/(640 " acres}}$

$\textcolor{w h i t e}{\text{XXX")=(4046.83 " sq. meters")/(1 " acre}}$
