what are a) the ratio of the perimeters and b) the ratio of the areas of the larger figure to the smaller figure? the figures are not drawn to scale. a. 13/3 and 169/9 b. 13/3 and 16/9 c. 16/3 and 169/9 d. 16/3 and 16/9
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
