| Given:

The perimeter of the rectangle is 48 centimeters.

One of its sides is 12 centimeters long.

Let’s find what the sum of one two identical sides is equal to:

12 + 12 = 24 centimeters.

Let’s find how much is the sum of two other identical sides:

48 – 24 = 24 centimeters.

Let’s calculate what one adjoining side is equal to:

24: 2 = 12 centimeters.

This value corresponds to the third answer.

Answer: 12 centimeters.
