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.

    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).


12. Find the actual distances in (a) and (b) and compare them.
    Explain your method.
