Find the perimeter and area of a 5 cm square.

1) Recall that a square is a rectangle with all four sides equal.

2) The perimeter of a square is equal to the sum of the lengths of all its sides. Therefore, the perimeter of the given square will be:

5 + 5 + 5 + 5 = 20 cm.

3) The area of a square is equal to the product of its two adjacent sides. This means that the area of a square with a side equal to 5 cm will be:

5 * 5 = 25 cm ^ 2.

Answer: the perimeter of the square is 20 cm, the area is 25 cm ^ 2.
