Measure the scale distance on the map
to the nearest 0.5 cm. Then use a proportion
to find the actual distance.

Enlarged Models
Scale drawings are also used to compare measures
of very small objects to a model that is enlarged.
The picture of the ladybug is an enlargement
in which 1 cm represents 1 mm.
Scale model is larger
than the real object.
Use the scale drawing of the ladybug to answer each question.
- What is the scale length of the ladybug’s body?
- What is the actual length of the ladybug’s body?
- What is the scale width of the ladybug’s body?
Measure to the nearest 0.5 cm. - Use a string and a metric ruler to find these distances
on the map at the top of the page: (a) scale distance
between Lansing and Piney along Route 6, Highway 9, and
Route 2; (b) “straight line” distance between Lansing and Piney.
Compare your measurements in (a) and (b). - Find the actual distances in (a) and (b) and compare them.
Explain your method.
