Let's say the length of the shorter side is x cm.

According to the given information, the length of the longer side is 2 cm longer than x, which is x + 2 cm.

Since a rectangle has two pairs of equal sides, the perimeter can be calculated by adding up the lengths of all four sides:

Perimeter = 2 * (length + width)

In this case, the perimeter is given as 20 cm, so we can set up the equation:

20 = 2 * (x + (x + 2))

Now, we can solve for x:

20 = 2 * (2x + 2)

10 = 2x + 2

10 - 2 = 2x

8 = 2x

4 = x

Therefore, the shorter side of the rectangle is 4 cm, and the longer side is 6 cm (4 + 2).
