Question

Three islands have a total area of 5321 mi island a is 3261 mi larger than island b and island b i 196 mi larger than c. What is the area of each island

Answer 1

A + B + C = 5321

 

A = B + 3261

 

B = C + 196 --> C = B - 196

 

Substituting the second and third equations into the first equation:

 

(B + 3261) + B + (B-196) = 5321

 

3B  + 3065 = 5321

 

3B = 2256

 

B = 752

 

A = B + 3261 = 752 + 3261 = 4013

 

C = 752 - 196 = 556

 

  752

4013  +

  556
