Answer:
1cm
Step-by-step explanation:
from the scale we know that
1cm on the map is equal to 300cms on the ground
Below I have made a table and used the unitary method.
Distance on Map Distance on ground
1cm 300cm
let width be = x width = 3m = 300cm
hence
width = ( 1 ×300)/ 300 = 1cm
Hope this helps
