Let the width of the rectangle be x.

Since the length of the rectangle is 3 longer than its width, the length of the rectangle is x + 3.

The perimeter of a rectangle is given by 2*(length + width), so the perimeter of this rectangle is 2*(x + 3 + x) = 66.

Simplifying the equation:
2*(2x + 3) = 66
4x + 6 = 66
4x = 60
x = 15

Therefore, the width of the rectangle is 15 and the length is x + 3 = 15 + 3 = 18.

So, the length of the rectangle is 18 and the width is 15.
