Answer

The ratio of the perimeters 1:2 The ratio of the areas 1:4

Work Step by Step

Find the corresponding side ratio. $\frac{2}{4}$=$\frac{1}{2}$ The ratio of the perimeters is equal to the ratio of the corresponding sides. $\frac{1}{2}$=$\frac{1}{2}$. This can be written as 1:2 also. The ratio of the areas is equal to the square of the ratio of the corresponding sides. $\frac{1^{2}}{2^{2}}$=$\frac{1}{4}$. This can also be written as 1:4
