Question 253739
Let the width of the rectangle be x.
Then, the length of the rectangle = 2x.
Perimeter of the rectangle is
           x+x+2x+2x = 90
                  6x = 90
                   x = 90/6
                   x = 15 feet
Therefore,the width of the rectangle =15 feet.
And, the length of the rectangle = 2x = 2*15 = 30feet
