Ответ:
a) find the ratio of the perimeters
the ratio of the perimeters is equal to the scale factor
scale factor=26/6> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3
b) find the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]²*area smaller figure
scale factor²=area larger figure/area smaller figure
the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²> 169/9
the answer Part b) is
169/9
the complete answer is
13/3 and 169/9
