Answer 1

12/4=3 см - сторона квадрата
3^2=9 см кв - площадь квдрата

одна сторона прямоугольника = 3 см
другая = 3*2=6 см
(3+6)*2=18 см - периметр прямоугольника

Perimeter and Area of a Square

To find the perimeter of a square, you simply multiply the length of one side by 4. In this case, the perimeter of a square with a side length of 12 cm would be 12 cm * 4 = 48 cm.

To find the area of a square, you square the length of one side. So, the area of a square with a side length of 12 cm would be 12 cm * 12 cm = 144 cm².

Perimeter of a Rectangle made of Two Squares

To find the perimeter of a rectangle made of two squares, we need to know the dimensions of the squares. Since the question does not provide the dimensions, we cannot calculate the exact perimeter. However, I can explain the general process.

Let's assume the side length of each square is x. The perimeter of one square would be 4x, and since there are two squares, the total perimeter would be 2 * 4x = 8x.

Please provide the dimensions of the squares so that I can calculate the perimeter of the rectangle more accurately.
