Answer 1

Ответ:

1 см2=100 мм2;1 дм2=100 см2;1 м2=100 дм2;1 км2=1 000 000 м2. 

  1)3 см2 10 мм2=310 мм2      

    2)6 дм2 05 см2=605 см2                                             3)2 м2 50 дм2=250 дм2                                             4)3 км2=3 000 000 м2           

Answer 2

1 см² = 100 мм²

1 дм² = 100 см²

1 м² = 100 дм²

1 км² = 1000000 м²

3 см² 10 мм² = 3 * 100 + 10 = 300 мм² + 10 мм² = 310 мм²

2 м² 50 дм² = 2 * 100 + 50 = 200 дм² + 50 дм² = 250 дм²

6 дм² 05 см² = 6 * 100 + 5 = 600 см² + 5 см² = 605 см²

3 км² = 3 * 1000000 = 3000000 м²

Answer 3

To solve these conversion problems, let's convert the given areas to the desired units:

1. 3 cm² to mm²: Since 1 cm = 10 mm, we can square this conversion factor to convert square centimeters to square millimeters: 3 cm² = 3 * (10 mm)² = 3 * 100 mm² = 300 mm²

2. 10 mm² to mm²: Since the given area is already in square millimeters, there is no conversion needed: 10 mm² = 10 mm²

3. 2 mm² 6 dm² 05 cm² to cm²: First, let's convert dm² to cm². Since 1 dm = 10 cm, we can square this conversion factor to convert square decimeters to square centimeters: 6 dm² = 6 * (10 cm)² = 6 * 100 cm² = 600 cm²

Now let's add all the areas in cm²: 2 mm² + 600 cm² + 5 cm² = 2 mm² + 605 cm² = 605 cm²

4. 2 m² 50 dm² to dm²: First, let's convert m² to dm². Since 1 m = 10 dm, we can square this conversion factor to convert square meters to square decimeters: 2 m² = 2 * (10 dm)² = 2 * 100 dm² = 200 dm²

Now let's add all the areas in dm²: 200 dm² + 50 dm² = 250 dm²

5. 3 km² to m²: Since 1 km = 1000 m, we can square this conversion factor to convert square kilometers to square meters: 3 km² = 3 * (1000 m)² = 3 * 1,000,000 m² = 3,000,000 m²

Therefore:

• 3см² = 300 mm²
• 10мм² = 10 mm²
• 2мм² 6дм² 05см² = 605 cm²
• 2м² 50дм² = 250 dm²
• 3км² = 3,000,000 m²
