To find the lengths of each side of the rectangle, let's assign variables to the lengths.
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).
