The perimeter of a rectangle is twice the sum of its sides.
In this case, the sum of the length and width of the rectangle will be:
28/2 = 14 cm.
Area is the product of length and width.
It is necessary to factor out the area.
In this case, the length and width can be equal:
2 * 24 = 48.
3 * 16 = 48.
4 * 12 = 48.
The first 3 pieces are not suitable because their sum is greater than the required value.
6 * 8 = 48.
We take the value of length equal to 8 cm, and width as 6 cm.
Answer: The sides of the rectangle are 8 and 6 cm.
