Answer:

  • The scale factor is 1 : 1500

-------------------------------------------

Corresponding dimensions are 26 mm and 39 m.

Find the scale factor:

  • 26 mm : 39 m =                     Given dimensions
  • 26 mm : 39 000 mm =          Convert to same unit, m to mm
  • 26 : 39000 =                         Cancel the unit (mm)
  • 26/26 : 39000/26 =              Divide both numbers by 26
  • 1 : 1500                                  Simplify
