.
scale of first map: 1cm:4000m=1:400000
scale of second map: 1:200000
Each dimension on the second map is twice that of the first map.
.
Is the given area 12 centimeters square or 12cm%5E2 (12 square centimeters)?
.
Case 1: Area would be 24cm by 24cm
Case 2: Area would be 48+cm%5E2
(doubling each dimension increases area 4 times)
