Answer 1

a) 1 dm²=10000mm²
     8,39 dm²=8,39*10000=83900mm²
b)1m²=1000000mm²
     2,14m²=2,14*1000000=2140000mm²
c)1km²=1000000m²
12,9km²=12,9*1000000=12900000m²
d)1m²=10000cm²
 3,1416m²=3,1416*10000=31416cm²
e) 1m² = 0,000001km²
    125,8m²=125,8*0,000001=0,0001258km²
f) 1 dam²=10000 dm²
    1,753 dam²=1,753*10000=17530dm²
