Question

A search plane covers 50 square miles of countryside.How many hectares does the plane search(to the nearest tenth)?

Answer 1

The plane has searched 12,950 hectares. the ratio between hectares to square miles is: 1 hectare is 2.471 acres

Answer 2

we know that

one square mile is equal to $258.999\ hectares$

so

by proportion

$\frac{258.999}{1} \frac{hectares}{square\ miles} =\frac{x}{50} \frac{hectares}{square\ miles}\\\\ x=50*258.999= 12,949.95\ hectares$

therefore

the answer is

$12,950\ hectares$
