Answer 1

Dear Student,

◆ Answer -

Scale of the map is 1 : 10^13.

● Explanation -

Let's convert both units to cm for easy calculations.

25,000 sq.miles = 25000 × (63360)^2 sq.inch

25,000 sq.miles = 10^14 sq.inch

Scale of the map is thus -

25,000 sq.miles on soil = 10 sq.inch on map

10^14 sq.inch on soil = 10 sq.inch on map

10^13 sq.inch on soil = 1 sq.inch on map

Therefore, scale of the map is 1:10^13.

Hope this helps you...

1 inch = 50 miles

Step-by-step explanation:

A scale drawing of the Mojave desert has an area of 10 square inches
