If the areas of two similar triangles are in the ratio 36 : 121, then what is the ratio of their corresponding sides?

6 : 11 11 : 5 6 : 5 5 : 12

6 : 11

Ratio of areas = 36 : 121 Ratio of corresponding sides = $\sqrt{36}$ : $\sqrt{121}$ = 6 : 11 Ratio of areas in similar triangles = ratio of square of corresponding sides
