You can invest it in the market, and try to get even more money. What they call "merching". You can buy some special armour, etc. you like. You can invest in improving some skill - some of the skills cost a lot of money. For example, to quickly train Smithing, 140M won't be enough to achieve level 99. Prayer is expensive, too (if you buy the big bones).
The question cannot be answered because it makes no sense. The area cannot be 140m and 10m. The area is a single number and its units should be square metres.
