The scale factor is
Explanation of Solution
Given:
The rectangle
The rectangle
Rectangle
Calculation:
Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio.
As the given two rectangles are similar so ratio of corresponding sides is constant.
The ratio of the corresponding sides are as:
The scale factor is the quotient of the dimensions of the rectangles. So the scale factor is given as:
The perimeter (sum of all sides) of two rectangles are calculated as:
The perimeter of both the rectangles are
Therefore, the scale factor is
