Answer
No. The summation of the highest elevations has no meaning.
Work Step by Step
- The summation of the land areas: $11,608,000+5,100,000+17,212,000+3,132,000+3,837,000+9,449,000+6,879,000=57,217,000$ square miles. What does it mean? It is the total land area of the world. So, we can evaluate the proportion of land area for each continent.
- The summation of the highest elevations: $19,340+16,066+29,035+7,310+18,510+20,320+22,834=283,415$ feet. What does it mean? Nothing.
