$0.680 mile ^{2}$

Work Step by Step

1. Convert acres into feet, [1 acre = 43,560 feet$^{2}$] $435 acres \times \frac{43560 ft^{2}}{ 1 acre} = 18,948,600 ft^{2}$ 2. $[(1mile)^{2}= (5280 feet)^{2}]$ Then, divide by 27,878,400 $ft^{2}/mile^{2}$ to convert into squaremiles $\frac{18,948,600 ft^{2}}{27,878,400 ft^{2}/mile^{2}} = 0.6797 mile^{2} \approx 0.680mile^2$
