1. Before proceeding with the solution of the problem, let us remember what the area of ​​a rectangle is. The area of ​​a rectangle is equal to the product of its two dimensions. The dimensions of a rectangle are its length and width.

2. Since we are given the area and length of one of the sides of the rectangle, therefore we can find out what the length of the second side of the given rectangle is equal to. To do this, it is necessary to divide its area by the length of the known side. So, let’s calculate the length of the second side of the rectangle if its area is 48 cm, and the length of the known side is 6 cm.

48/6 = 8 cm.

3. Adding the lengths of all sides of our rectangle, we find out what its perimeter is. So, let’s write the calculation:

8 + 8 + 6 + 6 = 28 cm.

Answer: The perimeter is 28 cm, and the length of the second side is 8 cm.
