Question

Длина кареледора 80дм,а ширена 9дм Хватит ли вдух кусков линолеума площадью 437 дециметров квадратных и385 дециметров квадратных ,чтобы застелить пол в этом коридоре

Answer 1

1)80×9=720(дм2)-площадь коридора
2)437+385=822(дм2)-площадь двух кусков
3)822-720=102(дм2)-останется

Answer 2

Calculating Linoleum Needed for the Corridor

To calculate whether the given amount of linoleum is sufficient to cover the floor of the corridor, we can use the formula:

Area = Length × Width

Given: - Length of the corridor = 80 dm - Width of the corridor = 9 dm - Area of linoleum piece 1 = 437 dm² - Area of linoleum piece 2 = 385 dm²

Let's calculate the total area of the corridor and compare it with the combined area of the linoleum pieces.

Calculations

The total area of the corridor: Area = 80 dm × 9 dm = 720 dm²

The combined area of the linoleum pieces: Total Linoleum Area = 437 dm² + 385 dm² = 822 dm²

Conclusion

The total area of the linoleum pieces (822 dm²) is greater than the area of the corridor (720 dm²). Therefore, the given linoleum pieces with a total area of 822 dm² would be sufficient to cover the floor of the corridor, which has an area of 720 dm².
