The perimeter of the square is 20 cm, find its sides. Draw a square and mark it with letters and find its area.

We know that a square is a rectangle in which all sides are equal. The perimeter is the sum of the lengths of all sides.
Accordingly, the side of the square will be equal to the perimeter divided by four.
1) 20: 4 = 5 (centimeters).
The area of the square is equal to the length of the side in the square.
2) 5² = 5 x 5 = 25 (cm²)
