Zorluk: KolayMap Enlargement and Reduction

A topographical map drawn to a Representative Fraction (R.F.) scale of 1:50,0001 : 50,000 is enlarged to twice its original linear dimensions. What is the scale of the new enlarged map?

  1. A
    1:100,0001 : 100,000
  2. 1:25,0001 : 25,000Cevap
  3. C
    1:12,5001 : 12,500
  4. D
    1:200,0001 : 200,000

Cevap

The scale of the new enlarged map is 1:25,0001 : 25,000.
Enlarging a map increases its scale, making the scale denominator smaller. When a map is enlarged to twice its linear size (2×2\times), the denominator of the original Representative Fraction (50,00050,000) is divided by 22, yielding a new scale of 1:25,0001 : 25,000.

Adım Adım Çözüm

1
Identify the original scale denominator and the linear enlargement factor.
Original scale denominator = 50,00050,000; Linear factor (kk) = 22.
Map enlargement alters the scale denominator inversely proportional to the linear change.
2
Calculate the new scale denominator by dividing the original denominator by the linear enlargement factor.
New denominator = 50,0002=25,000\frac{50,000}{2} = 25,000.
Enlarging a map makes features larger on paper, which corresponds to a larger scale with a smaller denominator.
3
State the new Representative Fraction (R.F.) scale.
New scale = 1:25,0001 : 25,000.
The new R.F. expresses the enlarged relationship between map distance and ground distance.
