Question

3а-3 м² 2 м²-200 см² 15 m²+200 дм²​

Answer 1

Ответ: 3а-3м²= тут я не понял что такое "а"

2м²-200см²=0

15м²+200дм²=15м²+20м²=35м²

Answer 2

To simplify the given expression, let's convert all the measurements to the same unit. Since square meters (m²) is the most commonly used unit for area, we'll convert all the measurements to square meters.

3a - 3m² + 2m² - 200cm² + 15m² + 200dm²

To convert centimeters to square meters, divide by 10,000 (since 1 m² = 10,000 cm²). To convert decimeters to square meters, divide by 100 (since 1 m² = 100 dm²).

3a - 3m² + 2m² - (200/10,000)m² + (15/1)m² + (200/100)m²

Simplifying the above expression, we get:

3a - m² + (0.02)m² + 15m² + 2m²

Combining like terms, we have:

3a + 18.02m²

Therefore, the simplified expression is 3a + 18.02m².
