Question

The combined land area of the countries A and B is 159159​,973 square kilometers. Country A is larger by 473473 square kilometers. Determine the land area of each country.

Answer 1

The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively

Explanation:

Let the area of Country B be x

We are given that Country A is larger by 473 square kilometers.

Area of Country A = x+473

Total area of both countries = x+x+473

Total area of both countries = 2x+473

We are given that The combined land area of the countries A and B is 159​,973 square kilometers.

So,
`2x+473=159​973`

`2x=159973-473`

`x=(159973-473)/(2)`

x=79750

Area of Country A = x+473=79750+473=80223 sq.km.

Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
