Question

Начерти два разных прямоугольника, периметр которых равен 8 см. Вычисли площади прямоугольника и сравни их. С обьяснениями

Answer 1

1 Прямоугольник) 1 сторона 6 см другая 2 см
2 Прямоугольник) 1 сторона  3 см другая 5 см

Площадь 1-го) 6*2=12(См2)
Площадь 2-го) 3*5=15(См2)

Сравнение) 12 см2<15 см2 - 12  см2 меньше 15 см2

Answer 2

Drawing Two Rectangles with Perimeter 8 cm

To compare the areas of two rectangles with a perimeter of 8 cm, let's start by drawing two different rectangles and calculating their areas.

Let's assume the sides of the first rectangle are 2 cm and 3 cm. The perimeter of this rectangle would be 2 + 2 + 3 + 3 = 10 cm. This doesn't satisfy the given perimeter of 8 cm.

Now, let's assume the sides of the second rectangle are 2 cm and 2 cm. The perimeter of this rectangle would be 2 + 2 + 2 + 2 = 8 cm, which matches the given perimeter.

Calculating the Areas of the Rectangles

The area of a rectangle is calculated using the formula: Area = length × width.

For the second rectangle with sides of 2 cm and 2 cm: Area = 2 cm × 2 cm = 4 square centimeters.

Comparison of the Areas

The area of the second rectangle is 4 square centimeters. Since we only have the area of one rectangle, we cannot directly compare it with another rectangle. However, based on the given information, the area of the second rectangle is 4 square centimeters.

Therefore, the area of the rectangle with sides of 2 cm and 2 cm is 4 square centimeters.
