Anastasy [175]

Answer:

Urban area = 58.27%

Suburban area = 34.83%

Rural area = 6.9%

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Total number of women = 290

Number of women in urban area = 169

Suburban area women = 101

Rural are women = 20

So, we can calculate the percentage of number of women from each area by using following formula,

Percentage = Women in specific area ÷ total women

So, percentage of Urban area = 169 ÷ 290 = 0.5827 or 58.27%

percentage of suburban area = 101 ÷ 290 = 0.3483 or 34.83%

percentage of rural area = 20 ÷ 290 = 0.0690 or 6.9%

Pie chart for the given information is attached below.
