Best ResponseYou've already chosen the best response.1Sorry 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.

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