Question

4. Задан прямоугольник со сторонами 5 см и 9 см. Найдите его периметр и площадь. Нарисуйте квадрат с таким же периметром и найдите его площадь.

Answer 1

Периметр-(9+5)*2=28
площадь-9*5=45
нарисуй квадрат со сторонами 7 см

Answer 2

S=5*9=45см
Р=5+5+9+9=28см
Сторона квадрат будет 7см
Sквадрат=49см

Answer 3

Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle with sides measuring 5 cm and 9 cm, we can use the following formulas:

- Perimeter of a rectangle: P = 2 * (length + width) - Area of a rectangle: A = length * width

Let's calculate the perimeter and area of the given rectangle:

1. Perimeter: - Length = 9 cm - Width = 5 cm - P = 2 * (9 + 5) = 2 * 14 = 28 cm

2. Area: - Length = 9 cm - Width = 5 cm - A = 9 * 5 = 45 cm²

Therefore, the perimeter of the rectangle is 28 cm and the area is 45 cm².

Square with the Same Perimeter

To draw a square with the same perimeter as the given rectangle, we need to find the length of each side of the square. Since the perimeter of the rectangle is 28 cm, the perimeter of the square should also be 28 cm.

To find the length of each side of the square, we can use the formula for the perimeter of a square: P = 4 * side length.

Let's calculate the length of each side of the square:

1. Perimeter: - P = 28 cm

2. Side length: - P = 4 * side length - 28 = 4 * side length - side length = 28 / 4 = 7 cm

Therefore, the length of each side of the square is 7 cm.

Area of the Square

To find the area of the square, we can use the formula for the area of a square: A = side length * side length.

Let's calculate the area of the square:

1. Side length: - Length = 7 cm

2. Area: - A = 7 * 7 = 49 cm²

Therefore, the area of the square with the same perimeter as the given rectangle is 49 cm².

Please note that the calculations and formulas provided above are based on the given dimensions of the rectangle and the properties of rectangles and squares.
