Answer

To find the percentage of France's population in the 30-35 year age group, we refer to the population pyramid. From the diagram, we observe that approximately 4% of males and 4% of females fall into this category. Therefore, we can calculate the total percentage as follows:

$4\% + 4\% = 8\%$

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

Answer

The population pyramids for France and India reveal significant differences.

France has a narrow base, indicating a low birth rate. This suggests a more aging population, with a higher percentage of individuals in older age categories. Factors contributing to this could include improved healthcare, family planning, and socio-economic conditions that favor smaller families.
India, on the other hand, features a broad base that indicates a high birth rate. This typically suggests a younger population with a larger proportion of children and young adults. The broad base is characteristic of developing countries, which face challenges such as limited access to education and healthcare, leading to higher birth rates.

Overall, the shapes of the pyramids highlight the demographic challenges each country faces: France must address an aging population, while India continues to manage rapid population growth.

Answer

To determine the area of the flags, we start with the dimensions provided. According to the scale of 1:23, we first need to convert the flag dimensions from the scaled measurements:

Length: 6 cm
Width: 3.9 cm

To find the actual dimensions:

Actual Length = 6 cm × 23 = 138 cm
Actual Width = 3.9 cm × 23 = 89.7 cm

Now, we calculate the area:

$\text{Area} = \text{Length} \times \text{Width} = 138 \text{ cm} \times 89.7 \text{ cm} = 12 378,60 \text{ cm}²$

This confirms that the area of the flag when completed will indeed be 12 378,60 cm².
