Question

My daughter has not really learned about square roots yet. How can I explain how to find the scale on this question in a simple way? Thank you

Answer 1

Given:

The area of the Mojave desert is 25000 square miles.

Scale of the map is:

25000 square miles on soil = 10 square inches on map

`25000\text{squaremiles = }10^(14)\text{ square inche }`
`10^(14)\text{ square inches on soil }=10\text{ square inches on map}`
`10^(13)\text{ square inches on soil =1 square inches on map}`
`1\colon10^(13)\text{ is the scale}`
