Answer 2

Let's convert the given values:

1 km² = 1,000,000 m² (1 square kilometer is equal to 1,000,000 square meters).

79 m² = 7,900,000 cm² (1 square meter is equal to 10,000 square centimeters).

7 hectares 50 ares = 750,000 m² (1 hectare is equal to 10,000 square meters, and 1 are is equal to 100 square meters).

660 minutes = 11 hours (1 hour has 60 minutes, so you can divide 660 by 60 to get the equivalent hours).

3 hours 25 minutes = 205 minutes (Add the 3 hours to 25 minutes to get the total minutes).

Keep in mind that for the conversion of 7 hectares 50 ares to square meters, you can follow these steps: 7 hectares = 7 * 10,000 = 70,000 square meters, and 50 ares = 50 * 100 = 5,000 square meters. Then, add these two values together to get 70,000 + 5,000 = 75,000 square meters.
