The perimeter of the rectangle is 24 cm. From five such rectangles, it turned out to add a square. What is the area of such a square?

The perimeter is the sum of all sides, then the sum of the 2 sides of a rectangle is equal to half of it:

24: 2 = 12 cm.

To get a square, five rectangles must be folded one under one.

The large side must be less than 12.

If we assume that it = 11cm, then the other side = 1cm.

Then we get a rectangle 5 by 11 cm, which does not suit us.

If we assume that the large side = 10, then the second = 2 cm.

We get a square 10 by 10 cm.

Find the area of the square:

10 * 10 = 100 cm ^ 2.

Answer: 100 cm ^ 2.
