Question

Найдите площадь прямоугольника со сторонами 12,5дм и 6,2дм.Решите эту же задачу,переводя дециметры в сантиметры.

Answer 1

Ответ:

Пошаговое объяснение:

Площадь прямоугольника= ширина*длина

1) 12,5*6,2= 77,5 дм.кв.

2) 12,5дм= 125 см

6,2дм= 62 см

125*62=7750 см.кв.

Answer 2

Sпрямоугольника=a*b, где а=12.5 дм, b=6,2дм.

S=12.5*6,2=77,5 дм^2

S=77.5*99,355=7700 см^2

Answer 3

Finding the Area of a Rectangle

To find the area of a rectangle, you multiply the length of one side by the length of the other side. In this case, we have a rectangle with sides measuring 12.5 dm and 6.2 dm.

The formula for finding the area of a rectangle is:

Area = length × width

Substituting the given values:

Area = 12.5 dm × 6.2 dm

To solve this problem, we can use the given values directly or convert the measurements to a different unit, such as centimeters.

Converting Decimeters to Centimeters

To convert decimeters (dm) to centimeters (cm), we need to remember that 1 decimeter is equal to 10 centimeters. Therefore, to convert from decimeters to centimeters, we multiply the measurement by 10.

In this case, we can convert the measurements of the rectangle from decimeters to centimeters before calculating the area.

The converted measurements are: - Length: 12.5 dm × 10 cm/dm = 125 cm - Width: 6.2 dm × 10 cm/dm = 62 cm

Now, we can use these converted measurements to find the area of the rectangle.

Calculating the Area in Centimeters

Using the converted measurements, the formula for finding the area of a rectangle becomes:

Area = length × width

Substituting the converted values:

Area = 125 cm × 62 cm

To find the area, we multiply the length (125 cm) by the width (62 cm):

Area = 125 cm × 62 cm = 7750 cm²

Therefore, the area of the rectangle with sides measuring 12.5 dm and 6.2 dm is 7750 cm².

Conclusion

The area of the rectangle with sides measuring 12.5 dm and 6.2 dm is 7750 cm².
