Since the length of the rectangle is 4 cm longer than the width, and the width of the rectangle is 3 cm, we get that the length will be:

3 + 4 = 7 cm.

To find the perimeter of a rectangle, add the lengths of all its sides. As a result, we get:

P = 7 + 3 + 7 + 3 = 10 + 10 = 20 cm.

Answer: 20 cm.
