Hi,

 

The length of a rectangle is 6 meters more than twice it's widthhighlight%28x%29. 

The perimeter is 90 meters.

  P = 2L + 2W = 90m

  0r   L + W = 45m        L = 2x%2B6

     (2x+6)+ x = 45

          3x = 39

           x = 13m, the width.  The length is 32m

and...

2%2A13m+%2B+2%2A32m+=+90m
