Answer 1

Если это знак умножить у тебя написан , тогда всё правильно . прикол в том что тебе на до переводить в ту систему единиц , в которую удобнее , вот и всё

Answer 2

To solve these expressions, let's convert all the measurements to the same units. We'll use meters (m) as the common unit for simplicity.

1. 2m * 300cm Convert cm to m: 300 cm = 3 m Calculation: 2 m * 3 m = 6 square meters (m²)

2. 8dm * 100mm Convert dm to m: 8 dm = 0.8 m Convert mm to m: 100 mm = 0.1 m Calculation: 0.8 m * 0.1 m = 0.08 square meters (m²)

3. 3000mm * 2m Convert mm to m: 3000 mm = 3 m Calculation: 3 m * 2 m = 6 square meters (m²)

4. 50cm * 7000m Convert cm to m: 50 cm = 0.5 m Calculation: 0.5 m * 7000 m = 3500 square meters (m²)

5. 6km * 900m Convert km to m: 6 km = 6000 m Calculation: 6000 m * 900 m = 5400000 square meters (m²)

6. 4km * 5000m Convert km to m: 4 km = 4000 m Calculation: 4000 m * 5000 m = 20000000 square meters (m²)

7. 20m * 2000cm Convert cm to m: 2000 cm = 20 m Calculation: 20 m * 20 m = 400 square meters (m²)

Therefore, the results are:

1. 2m * 300cm = 6 square meters (m²)
2. 8dm * 100mm = 0.08 square meters (m²)
3. 3000mm * 2m = 6 square meters (m²)
4. 50cm * 7000m = 3500 square meters (m²)
5. 6km * 900m = 5400000 square meters (m²)
6. 4km * 5000m = 20000000 square meters (m²)
7. 20m * 2000cm = 400 square meters (m²)
