Two triangles are similar and have a ratio of similarity of 2:3. What is the ratio of their perimeters and the ratio of their areas?
perimeter: 2:3 area: 4:6 perimeter: 4:6 area: 2:3 perimeter: 2:3 area: 4:9 perimeter: 4:9 area: 2:3
Which do you believe is the correct choice?
perimeter: 4:9 area: 2:3
If you have to two sides a and b of two similar triangles, then the ratio of the perimeters is a:b the ratio of the areas are a^2: b^2
