Question

Eliana drew a scale drawing of a house. The garage is 10 centimeters wide in the drawing. The actual garage is 5 meters wide. What scale factor does the drawing use?Simplify your answer and write it as a ratio, using a colon.

Answer 1

Step-by-step explanation

As the garage is 10 centimeters wide in the drawing, and the actual wide is 5 meters, we first need to represent the centimeters in meter units.

10 centimeters ---> 0.1 meters

Now, dividing both sizes give us the scale factor:

`\text{Scale factor=}(0.1)/(5)=(1)/(50)=1\colon50`

The scale factor is 1:50
