If the areas of two similar triangles are in the ratio 4 : 9, then their corresponding sides are in the ratio 1. 9 : 4 2. 3 : 2 3. 2 : 3 4. 16 : 81

Given, ratio of the areas of the two similar triangles = 4 : 9 We know that, the ratio of the areas of two similar triangles is equal to the ratio of the square of their corresponding sides. = 2 : 3. Hence, Option 3 is the correct option.
