Question

Pls help I’m confused

The scale of a map is 1
inch : 10 miles.
If a road is 3%2 inches on
the map, what is the
actual length of the
road? If a pond is 15
miles long, what is the
length of the pond on
the map?

Answer 1

1 inch= 10 miles

1 inch * 1 inch = 1 in^2 = 10 miles * 10 miles = 100 miles^2

so

1 in^2 is 100 mi^
