Question

Реши задачу и запиши ответ Найдите площадь квадрата, если его периметр равен прямоугольника со сторонами 12 см и 6 см

Answer 1

Р кв = Р пр = 12+12+6+6 = 36см
сторона у крадрата = 36/4 = 9см
S кв = 9*9 =81 см²

Answer 2

Problem:

Найдите площадь квадрата, если его периметр равен прямоугольника со сторонами 12 см и 6 см.

Solution:

To find the area of a square, we need to know the length of its side. Since the perimeter of the square is equal to the perimeter of the rectangle, we can find the length of the side of the square by dividing the perimeter of the rectangle by 4.

Let's calculate the perimeter of the rectangle first. The perimeter of a rectangle is given by the formula: P = 2 * (length + width). In this case, the length of the rectangle is 12 cm and the width is 6 cm. Plugging these values into the formula, we get:

P = 2 * (12 + 6) = 2 * 18 = 36 cm

Now, we can find the length of the side of the square by dividing the perimeter of the rectangle by 4:

Side of the square = Perimeter of the rectangle / 4 = 36 cm / 4 = 9 cm

Finally, we can calculate the area of the square by squaring the length of its side:

Area of the square = (Side of the square)^2 = 9 cm * 9 cm = 81 cm^2

Therefore, the area of the square is 81 square centimeters.

Answer:

Ответ: Площадь квадрата равна 81 квадратным сантиметрам.
