Question

409дм2-450см2×2= перевести в метрах квадратных

Answer 1

Решение:
1м²=100дм²
409дм²:100дм²=4,09м²
1м²=10 000см²
450см²*2=900см²=900см² : 10 000см²=0,09м²
4,09м²-0,09м²=4м²

Ответ: 4м²

Answer 2

Calculating Area and Converting Units

To solve the given expression 409 m² - 450 cm² × 2 and convert the result to square meters, we'll follow these steps:

1. Convert 450 cm² to square meters. 2. Perform the arithmetic operation. 3. Express the result in square meters.

Step 1: Convert 450 cm² to Square Meters

To convert square centimeters to square meters, we can use the conversion factor: 1 m² = 10,000 cm².

Converting 450 cm² to square meters: 450 cm² * (1 m² / 10,000 cm²) = 0.045 m²

450 cm² is equal to 0.045 m² .

Step 2: Perform the Arithmetic Operation

Now, let's perform the arithmetic operation: 409 m² - (0.045 m² × 2) = 409 m² - 0.09 m² = 408.91 m²

The result of 409 m² - 450 cm² × 2, when converted to square meters, is approximately 408.91 m².

Therefore, the expression 409 m² - 450 cm² × 2 is approximately equal to 408.91 m² when converted to square meters.
