and the perimeter of cm. Calculate the scale factor of similarity of to and the perimeter of .
The scale factor of similarity of one polygon with respect to another similar polygon is the ration of the lengths of corresponding sides.
Since and are corresponding sides in polygons and , the scale factor of similarity of
to is . Use the fact that the ration of the perimeter of to the perimeter of is
equal to the scale factor to determine the perimeter of .
Thus, the scale factor is , and the perimeter of is cm.
