Sow barley

Farmers wanted to sow barley within 13 days. Due to the excellent weather, they managed to exceed the daily plan of sowing by 2 ha and therefore finished sow grain in 12 days. How many hectares of land did they sow with barley?

Correct result:

x =  312 ha

Solution:

 x=13 d x=12 (d+2)  13dx=0 12dx=24  d=24 x=312=312 ha
