Question

On the blueprint of a house, 40 millimeters represents 6 meters. The length of the living room is 50 millimeters on the blueprint. What is the actual length of the living room?

Answer 1

Answer:

Convert the meters to millimeters

1m = 1000mm

6m = 6000mm

40mm represents 6000mm

Find the scale factor

6000/40 = 150

This means 40 * 150 = 6000

Yup find what 50mm represents:

50 * 150 = 7500

7500mm

7.5m
