The ratio between the lengths of 2 rectangles is the same between their perimeters
Since the ratio between the length of rectangle A and the length of rectangle B is 7: 3, then
The ratio between the perimeter of rectangle A to the perimeter of rectangle B is 7: 3 too
Since the perimeter of rectangle A is 540, then
We will write them as a fraction
By using the cross multiplication
Divide both sides by 7
Round it to the nearest tenth
The perimeter of the smaller rectangle B is 231.4 inches

Step-by-step explanation:
From the information given, the population is divided into sub groups. Each group would consist of citizens picking a particular choice as the most important problem facing the country. The choices are the different categories. In this case, the null hypothesis would state that the distribution of proportions for all categories is the same in each population. The alternative hypothesis would state that the distributions is different. Therefore, the correct test to use to determine if the distribution of "problem facing this country today" is different between the two different years is
A) Use a chi-square test of homogeneity.
