Question

the combined land area of the countries A sand B is 190,973 square kilometers. Country A is larger by 373 square kilometers. Determine the land area of each country. 

Answer 1

You know country A is 373 larger than B, so we can set A = B + 373

 

A + B = 190,973

 

We can go ahead and substitute (B + 373) in for A.

 

(B + 373) + B = 190,973

2B + 373 = 190,973

2B = 190,600

B = 95,300 km^2

 

Since you know A is just 373 larger than B,

 

A = 95,300 + 373 = 95,673 km^2
