Answer:

≅ 586.8

Explanation:

Take x to be the width, if the length is 5x bigger than the width, then this can be shown by 5x.

The total perimeter is:

(2 * x) + (2 * 5x) because each side has another parallel one.

This means that 2x + 10x = 130

12x = 130

Divide both sides by 12:

`(12x)/(12) = (130)/(12)`

x =
`(65)/(6)`

So the area = length * width

x * 5x = area

Substitute the values in:

`(65)/(6) * (5*(65)/(6))` = 586.8055... ≅ 586.8

So the approximate area is 586.8

Hope this helps!
