The values that complete the conversions are 
a = 10000
b = 100
c = 1000000
<h3>Conversion of units </h3>
From the question, we are to complete the given conversions 
i) 
1 m² = a cm²
NOTE: 1 m² =  10000 cm²
∴ a = 10000
ii)
1 cm² = b mm²
NOTE: 1 cm² = 100 mm²
∴ b = 100
iii)
1 km² = c m²
NOTE: 1 km² = 1000000 m²
∴ c = 1000000
Hence, the values that complete the conversions are 
a = 10000
b = 100
c = 1000000
