Question

Oliver drew a scale drawing of a swimming pool. In real life, the pool is 39 meters long. It is 26 millimeters long in the drawing. What is the scale of the drawing?

Answer 1

• 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
