I would set this up as a a proportion: 5 c m 17 c m · x 272 c m
17x = 1360 x = 20 cm
The corresponding length of square y is 20 cm, as it is four times the length of square x, which is 5 cm. This relationship is due to the fact that the areas of similar figures are proportional to the square of their corresponding lengths. Therefore, given that the areas of squares x and y are 17 cm² and 272 cm² respectively, the calculated length of square y is consistent with this ratio.
