Question 69

In the figure, the comparative areas of the countinents are given.

What is the ratio of the areas of

a) Africa to Europe?

b) Australia to Asia?

c) Antarctica to combined area of North America and South America?

Answer 1

From the above figure, we find that:

Area of North America = 17 sq units
Area of Europe = 10 sq units
Area of South America = 18 sq units
Area of Africa = 26 sq units
Area of Asia = 44 sq units
Area of Australia = 8 sq units
Area of Antarctica = 13 sq units

a) Ratio of Area of Africa to Europe

= $\frac{\text{Area of Africa}}{\text{Area of Europe}}$
= $\frac{26}{10}$

= $\frac{13}{5}=13:5$ [on dividing numerator and denominator by 2]

b) Ratio of area of Australia to Asia

= $\frac{\text{Area of Australia}}{\text{Area of Asia}}$
= $\frac{8}{44}$
= $\frac{2}{11}=2:11$ [on dividing numerator and denominator by 4]

c) Ratio of Antartica to combined area of North America and South America

= $\frac{\text{Area of Antartica}}{\text{Combined area of North and South America}}$
= $\frac{13}{17+18}$

= $\frac{13}{35}=13:35$
