Solution
The correct option is D5:4 The ratio of areas of given similar triangles =25:16
And we know that, ratio of areas of two triangles is same as the ratio of squares of their corresponding sides ∴ Ratio of the corresponding sides of the similar triangles =√2516=54=5:4 ∴ The ratio of the perimeters of given similar triangles =5:4
