Answer 2

Let's convert the given measurements and perform the calculations step by step:

1. Convert 900000000 mm to other units:

   • 900000000 mm = 90000000 cm (since 1 meter = 100 centimeters)
   • 90000000 cm = 9000000 dm (since 1 meter = 10 decimeters)
   • 9000000 dm = 900000 m (since 1 meter = 1 meter)
   • 900000 m = 900 km (since 1 kilometer = 1000 meters)

2. Convert 4 km 3 m 6 dm 9 cm 7 mm to meters:

   • 4 km = 4 * 1000 m = 4000 m
   • 3 m = 3 m
   • 6 dm = 6 * 0.1 m = 0.6 m
   • 9 cm = 9 * 0.01 m = 0.09 m
   • 7 mm = 7 * 0.001 m = 0.007 m

   Adding them all together: 4000 m + 3 m + 0.6 m + 0.09 m + 0.007 m = 4003.697 m

3. Convert 6 dm 9 cm 7 mm to meters:

   • 6 dm = 6 * 0.1 m = 0.6 m
   • 9 cm = 9 * 0.01 m = 0.09 m
   • 7 mm = 7 * 0.001 m = 0.007 m

   Adding them all together: 0.6 m + 0.09 m + 0.007 m = 0.697 m

4. Convert 9 cm 7 mm to meters:

   • 9 cm = 9 * 0.01 m = 0.09 m
   • 7 mm = 7 * 0.001 m = 0.007 m

   Adding them together: 0.09 m + 0.007 m = 0.097 m

5. Convert 7 mm to centimeters:

   • 7 mm = 7 * 0.1 cm = 0.7 cm

6. Convert 2 km 215 m 4 dm 9 cm 2 mm to meters:

   • 2 km = 2 * 1000 m = 2000 m
   • 215 m = 215 m
   • 4 dm = 4 * 0.1 m = 0.4 m
   • 9 cm = 9 * 0.01 m = 0.09 m
   • 2 mm = 2 * 0.001 m = 0.002 m

   Adding them all together: 2000 m + 215 m + 0.4 m + 0.09 m + 0.002 m = 2215.492 m

7. Multiply 2 km 215 m 4 dm 9 cm 2 mm by 5215:

   • 2215.492 m * 5215 = 11558866.98 m

8. Convert 6 km 3000 m 100000 mm to meters:

   • 6 km = 6 * 1000 m = 6000 m
   • 3000 m = 3000 m
   • 100000 mm = 100000 * 0.001 m = 100 m

   Adding them all together: 6000 m + 3000 m + 100 m = 9100 m

9. Multiply 11558866.98 m by 11:

   • 11558866.98 m * 11 = 127147536.78 m

10. Convert 215 m 400 dm 5000 mm to meters:

    • 215 m = 215 m
    • 400 dm = 400 * 0.1 m = 40 m
    • 5000 mm = 5000 * 0.001 m = 5 m

    Adding them all together: 215 m + 40 m + 5 m = 260 m

11. Multiply 260 m by 260000:

    • 260 m * 260000 = 67600000 m

12. Convert 4800000 cm to meters:

    • 4800000 cm = 4800000 * 0.01 m = 48000 m

13. Multiply 48000 m by 34:

    • 48000 m * 34 = 1632000 m

14. Convert 34 m 70 dm 300 cm 2000 mm to meters:

    • 34 m = 34 m
    • 70 dm = 70 * 0.1 m = 7 m
    • 300 cm = 300 * 0.01 m = 3 m
    • 2000 mm = 2000 * 0.001 m = 2 m

    Adding them all together: 34 m + 7 m + 3 m + 2 m = 46 m

15. Multiply 46 m by 6 m 7 dm 2 cm:

    • 46 m * (6 m + 7 * 0.1 m + 2 * 0.01 m) = 46 m * (6 m + 0.7 m + 0.02 m) = 46 m * 6.72 m = 309.12 m²

16. Multiply 6 m 7 dm 1 cm by 6 m 7 dm:

    • (6 m + 7 * 0.1 m + 1 * 0.01 m) * (6 m + 7 * 0.1 m) = (6 m + 0.7 m + 0.01 m) * (6 m + 0.7 m) = 6.71 m * 6.7 m = 44.917 m²

Now, let's compare the results:

1. 900000000 mm = 90000 cm = 9000 dm = 900 m = 0.9 km
2. 4 km 3 m 6 dm 9 cm 7 mm = 4003.697 m
3. 6 dm 9 cm 7 mm = 0.697 m
4. 9 cm 7 mm = 0.097 m
5. 7 mm = 0.7 cm
6. 2 km 215 m 4 dm 9 cm 2 mm = 2215.492 m
7. 2 km 215 m 4 dm 9 cm 2 mm * 5215 = 11558866.98 m
8. 6 km 3000 m 100000 mm = 9100 m
9. 11558866.98 m * 11 = 127147536.78 m
10. 215 m 400 dm 5000 mm = 260 m
