The perimeter of the rectangle is 140.
Given that,
Now based on the above information,
We know that
[tex]Area\ of\ the\ rectangle = length \times width\\\\600 = 6x \times x \\\\600 = 6x^2\\\\x^2 = 100[/tex]
x = 10
That means the width be 10m
And, the length be 60m
Now the perimeter of the rectangle should be
[tex]= 2 \times (Length+width)\\\\= 2\times (10 + 60)\\\\= 2 \times 70[/tex]
= 140m
Therefore we can conclude that the perimeter of the rectangle is 140.
