12. convert the following scales to numeric ratio scales, showing your calculations: a) one inch to 3500 feet; b) one centimeter to 22 kilometers. (1 point) 13. a landform is 8 em long on a map and is 213 km long in the real world. what must the ratio scale of the map be? (i. e., in the ratio 1: x, what is (1 point)

12.

a) scale =

b) scale =

13. X = 2,662,500

Explanation:

Given:

a) 1 in to 3500 feet

i.e

scale =

or

scale =

or

scale =

b) one centimeter to 22 kilometers

i.e

scale =

or

scale =

or

scale =

13.Given:

length of landform on map = 8 cm

length of the landform in real world = 213 km

thus,

scale =

or

scale =

or

scale =

or

scale =

Hence, X = 2,662,500
