Thank you!

Answer 1

Given:

Given that the area of the rectangle is
`2.48 * 10^(12) \ cm^2`

The length of the rectangle is
`6.2 * 10^6 \ cm`

We need to determine the perimeter of the rectangle.

Width of the rectangle:

The width of the rectangle can be determined using the formula,

`Area = length * width`

Substituting the values, we have;

`2.48 * 10^(12)=6.2 * 10^6 * width`

Dividing both sides of the equation by
`6.2 * 10^4`, we get;

`0.4 * 10^6=width`

Thus, the width of the rectangle is
`0.4 * 10^6 \ cm`

Perimeter of the rectangle:

The perimeter of the rectangle can be determined using the formula,

`P=2(l+w)`

Substituting the values, we get;

`P=2[(6.2 * 10^6)+(0.4 * 10^6)]`

`P=2(6.6 * 10^6)`

`P=13.2 * 10^6 \ cm`

Thus, the perimeter of the rectangle is
`13.2 * 10^6 \ cm`
