| **Given a rectangle is divided into two equal squares by a dotted line. The perimeter of the rectangle is 42 cm, write what will be the perimeter of the square?**

Pp = 42 cm

Rkv =?

It would be good to represent the conditions of the task in the form of a picture. We will try to reason. The short side in the rectangle matches the side of the square. Let’s denote it – a. Two squares are laid along the long side. Long side – 2a. Means:

Pp = a + 2a + a + 2a = 6a or 6a = 42

Let’s find a:

a = 7

Find the perimeter of the square:

Rkv = 4a = 28

Answer: 28 cm perimeter of the square.
