Question

Площадь прямоугольника равна 48 см2(квадрат),а ширина его равна 2 см. Чему равен периметр и площадь квадрата, сторона которого в 4 раза меньше длины прямоугольника? Помогите пожалуйста

Answer 1

Ответ:

1) 48 / 2 = 24(см) - длинна

2) 24 / 4 = 6(см) - сторона квадрата

3) 6 * 4 = 24(см) - периметр квадрата

4) 6 * 6 = 36(см2) - площадь квадрата

Answer 2

Calculation of Rectangle's Perimeter and Area

To find the perimeter and area of a rectangle, we need to know the length and width of the rectangle. In this case, the area of the rectangle is given as 48 cm², and the width is given as 2 cm.

Let's calculate the length of the rectangle first using the formula for the area of a rectangle:

Area of a rectangle = length × width

Substituting the given values: 48 cm² = length × 2 cm

To find the length, we can rearrange the equation: length = 48 cm² / 2 cm

Calculating the length: length = 24 cm

Now that we have the length and width of the rectangle, we can calculate its perimeter and area.

Perimeter of a rectangle = 2 × (length + width)

Substituting the values: Perimeter = 2 × (24 cm + 2 cm)

Calculating the perimeter: Perimeter = 2 × 26 cm Perimeter = 52 cm

Area of a rectangle = length × width

Substituting the values: Area = 24 cm × 2 cm Area = 48 cm²

So, the perimeter of the rectangle is 52 cm and the area is 48 cm².

Calculation of Square's Perimeter and Area

Now, let's calculate the perimeter and area of a square whose side length is 4 times smaller than the length of the rectangle.

The length of the rectangle is 24 cm, so the side length of the square will be 24 cm / 4 = 6 cm.

Perimeter of a square = 4 × side length

Substituting the value: Perimeter = 4 × 6 cm

Calculating the perimeter: Perimeter = 24 cm

Area of a square = side length × side length

Substituting the value: Area = 6 cm × 6 cm

Calculating the area: Area = 36 cm²

Therefore, the perimeter of the square is 24 cm and the area is 36 cm².
