~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



        The solution in the post by @mananth is incorrect due to arithmetic errors.

        I came to bring a correct solution.



let x be the width
4x will be the length
4x*x = 16
4x^2 = 16
x^2 = 4
x = 2 or -2
the width is 2 meters and the length is 2*4 = 8 meters
the perimeter = 2 + 8 + 2 + 8 = 20 meters.    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>
