Answer 2

Answer: The perimeter of rectangle is
`1.58* 10^6`

Explanation:

Given: Area of rectangle =
`1.45 * 10^(11)`

Width of rectangle =
`2.9 * 10^(5)`

As we know area of a rectangle is given by

`Area = Length * Breadth`

So we have

`1.45 * 10^(11)= Length * 2.9 * 10^(5)\\\\\Rightarrow Length = (1.45 * 10^(11))/(2.9 * 10^(5)) \\\\\Rightarrow Length = 0.5 * 10^6 = 5 * 10 ^5`

Now as we know

`Perimeter = 2(Length +breadth)\\\\\`

Length =
`5 * 10^5`

Breadth =
`2.9 * 10^(5)`

Therefore

`Perimeter = 2(5 * 10^5+ 2.9 * 10^5)\\\\\Rightarrow Perimeter = 2* 10^5(5+2.9)\\\\\Rightarrow Perimeter = 15.8 * 10^5 = 1.58 * 10^6`

Hence,the perimeter of rectangle is
`1.58* 10^6`
