Question

A set designer builds a model of a stage and the different pieces of furniture on it. He uses a scale of 5 cm to 1m. The length of a table is 1.4m. What is the length of the model?

Answer 1

To solve this problem, we simply have to use ratio and proportion. We know that for every 5 cm, we have 1 m therefore the factor to use is:

5 cm / 1 m

 

SO for a table length of 1.4 m, the model length should be:

model = (5 cm / 1 m) * 1.4 m

model = 7 cm

 

Answer:

7 cm
