Sorry but the ratio of the sides squared would be the ratio of the areas. And so the square root of the ratio of the areas would be the ratio of the sides.

Mertsj Group TitleBest ResponseYou've already chosen the best response.1
So if the ratio of the areas is 36/100, the ratio of the sides is 6/10
