Answer
Ratio of the perimeters 4:3
Ratio of the areas 16:9
Work Step by Step
Set up a ratio of the corresponding sides.
12:9
Reduce the ratio by dividing each number by 3.
4:3
The ratio of the perimeter is the same as the ratio of corresponding sides.
4:3 = 4:3
The ratio of the areas is the square of the ratio of corresponding sides.
$4^{2}$:$3^{2}$=16:9
