Answer:

  • 57 million square miles

Step-by-step explanation:

Let the area of water is w and area of land is l.

Their ratio is:

  • w/l = 7/3

or

  • 133 / l = 7/3

Find the value of l

  • l = 133*3/7
  • l = 57 million square miles

Let that be x

  • 133/x=7/3
  • 7x=399
  • x=399/7
  • x=57M mi²
