Answer:

1060 feet

Step-by-step explanation:

The computation of the perimeter of the rectangle is as follows;

As we know that

Perimeter of the rectangle = 2 × ( length + width)

where

Length of x = 5

And, the width be 5x^3 - 4x^2

= 5(5)^3 - 4(5)^2  

= 625 - 100  

= 525

Now the perimter is

= 2 × (5 + 525)

= 1060 feet
