![9.6*10^7\ mi^2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/u1dgfkvu39nvlpetq878lpgskuqi9qpb5r.png)
Explanation:
Let
x -----> area covered by the Atlantic Ocean
y -----> area covered by the Pacific Ocean
we know that
The area that covers the Atlantic Ocean and Pacific Ocean is equal to the sum of the area covered by the Atlantic Ocean and the area covered by the Pacific Ocean
so
![x+y](https://img.qammunity.org/2020/formulas/mathematics/middle-school/boqbnwzm2z1wq96eo70cmqhh6zhxmdmook.png)
we have
![x=3.2*10^7\ mi^2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ch9hk9n5a60bcucraa9t8esnbb7w0nv3tt.png)
![y=6.4*10^7\ mi^2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/usspt2z1pfugil1sx1vmj2w75o4e3jfhu6.png)
substitute
![x+y=3.2*10^7\ mi^2+ 6.4*10^7\ mi^2=9.6*10^7\ mi^2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/lficizzhen6kt5vwaibjsbaoaskpub010z.png)
