Answer 1

Hope this helps you.

Answer 2

`\bf so \begin{cases} A=\textit{area of first desert}\\ B=\textit{area of second desert}\\ --------------\\ \textit{whatever long B is, A is 6 times that much} \\\\ A=\boxed{6B}\\ --------------\\ \textit{now, their sum is }1,400,000\textit{ that is} \\\\ A+B=1,400,000\implies \boxed{6B}+B=1,400,000 \end{cases}`

solve for "B" to see how long is the B desert,

now, what about desert A? or the first desert? well, is 6B :)
