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%
