Answer

To determine the percentage of France's population in the age category of 30-35 years, observe the population pyramid.

From the graph, both the male and female populations in that age bracket appear to be around 4%. Therefore, combining both genders:

$ext{Percentage} = 4 ext{ ext{%}} + 4 ext{ ext{%}} = 8 ext{ ext{%}}$

Thus, approximately 8% of France's population falls in the category of 30-35 years.

Answer

When analyzing the population pyramids of France and India, we notice a significant difference in their shapes which hints at the underlying demographic trends:

France has a narrow based pyramid, suggesting it has a low birth rate. This indicates a stable population that does not grow significantly over time, often characteristic of developed countries.
India, on the other hand, exhibits a broader base, indicative of a high birth rate. This suggests that India has a younger population, representing a growing demographic that is typically seen in developing countries.

In conclusion, the shape of the pyramids reflects the varying birth rates and demographic structures of France and India.

Answer

To find the actual dimensions of the flags using the scale of 1 : 23:

For length:

Given that the length on the flag is 6 cm:

$ext{Actual Length} = 6 ext{ cm} imes 23 = 138 ext{ cm}$
For width:

Given that the width on the flag is 3.9 cm:

$ext{Actual Width} = 3.9 ext{ cm} imes 23 = 89.7 ext{ cm}$
Now, to calculate the area:

$ext{Area} = ext{Length} imes ext{Width} = 138 ext{ cm} imes 89.7 ext{ cm} = 12,378.60 ext{ cm}^2$

Thus, the area of each flag will indeed be 12,378.60 cm².
