Answer

16 km² + 106ha + 17,459 m²   =  17,077,459 m²

Explanation

All we need is to convert the units into the same units then add them together.

5sq.km 95ha 8449sq.m +11sq.km 11ha 9010sq.m

5sq.km + 11sq.km = 16 km²

95ha + 11ha = 106ha

8449sq.m + 9010sq.m = 17,459 m²

∴ 5sq.km 95ha 8449sq.m +11sq.km 11ha 9010sq.m = 16 km² + 106ha + 17,459 m²

1 km² = 1000000 m²

16 km² = 16 × 1000000

           = 16,000,000 m²

1 ha = 1000 m²

106 ha = 106 × 10000

           = 1,060,000 m²

∴ 16,000,000 m² + 1,060,000 m² + 17,459 m² = 17,077,459 m²
