Question

The area of the southern ocean is about 7.85 x 10^6 square miles. The difference between the areas of the indian ocean and the southern ocean is about 1.865 x 10^7 square miles. Explain how to find the area of the indian ocean. Then find the area.

Answer 1

The answer to your question is: 2.65 x 10⁷ square miles

Explanation:

Data

Southern ocean area = 7.85 x 10⁶ square miles

Difference between areas Indian ocean = 1.865 x 10⁷ square miles

and the southern ocean

Process

a) To find the area of the Indian ocean we need to sum of the values of the area of the Southern ocean and the area of the difference between the Indian ocean and the southern ocean.

b)

Area of the Indian Ocean = 1.865 x 10⁷ + 7.85 x 10⁶

= 2.65 x 10⁷ square miles

Answer 2

The area of the Indian ocean is
`2.65* 10^7`

Explanation:

Given : The area of the southern ocean is about
`7.85* 10^6` square miles. The difference between the areas of the Indian ocean and the southern ocean is about
`1.865* 10^7` square miles.

To find : Explain how to find the area of the Indian ocean. Then find the area.

Solution :

The area of the southern ocean is about
`7.85* 10^6` square miles.

i.e.
`A_s=7.85* 10^6`

The difference between the areas of the Indian ocean and the southern ocean is about
`1.865* 10^7` square miles.

i.e.
`A_i-A_s=1.865* 10^7`

Substitute the value of
`A_s`

`A_i-7.85* 10^6=1.865* 10^7`

`A_i=1.865* 10^7+7.85* 10^6`

`A_i=1.865* 10^7+0.785* 10^7`

`A_i=(1.865+0.785)* 10^7`

`A_i=2.65* 10^7`

Therefore, The area of the Indian ocean is
`2.65* 10^7`
