Question

Answer 1

Given that the area of the mojave desert is 25,000 square miles and a scale drawing of the mojave desert has an area of 10 square inches.

The scale of the map is given by

$\sqrt{25,000} : \sqrt{10} = \sqrt{2,500\times10} : \sqrt{10} \\ \\ =50 \sqrt{10} : \sqrt{10} =50:1$

Therefore, the scale of the drawing is 50 : 1.
