I was happy when my dad bought a farm that worth #5 million. So we work very hard to develop the farm and got more yield. After many years the farm increase in it value. The initial size of the farm filled(covered) with grown grain is 1000m^2 i.e an hectare. After the development we where able to grow grains covering 5/6 of the total area of the farm. What is the increment if the total area of the farm is 6000m^2
